A bicycle is going 2.6 m/s when it speeds up to 15.4 m/s in 8 seconds. What is the acceleration?
Answer:
acceleration is 1.6 m/s^2
Explanation:
This is a question involving Kinematics so we can use one of the kinematic equations.
Given info: Vi= 2.6 m/s. Vf= 15.4 m/s. T= 8s
We need to solve for acceleration
The best equation to use is (Vf = Vi + at) as it contains all the info we need to solve for acceleration.
Now substitute the values given into the equation.
Vf = Vi + at >> 15.4 = 2.6 + a8
Now solve for a by rearranging the equation.
15.4 -2.6= 8a >> 12.8=8a >> 12.8/8= 8a/8 >> 1.6 =a
NOTES:
Acceleration is the rate of increase of velocity
Vf is final velocity or velocity after acceleration/de-accaeleration occurs
Vi is intial velocity or velocity before acceleration or de-accaeleration occurs
Time is time it took for a certain motion to occur.

It lands on the ground with a final speed of 6.0 m/s
How long is the ball in the air?
Round the answer to two significant digits
Answer:
The correct answer is t = 0.92s
Explanation:
Initial velocity v0 = 3.0 m/s
Displacement Δy = ?
Acceleration a = -9.8m/s2
Final velocity v = -6.0m/s
Time t=? Target unknown
We can use the kinematic formula missing Δy to solve for the target unknown t:
V=v0+at
We can rearrange the equation to solve to t:
V-v0=at
t= v-v0/a
Substituting the known value into the kinematic formula gives:
t= (-6.0m/s)-(3.0m/s)
————————————
-9.8m/s2
= -9m/s
—————-
-9.8m/s2
=0.92s

A force of 200N is creating a pressure of 50Pa on a surface. Calculate the area of the surface.
Answer:
4kg
Explanation:
pressure=50pa
force=200N
Area=?
now,
pressure=force/area
50=200/area
area=200/50
area=4kg
The pressure is the forces acting on a given area. Hence, the area of the surface with a pressure of 50 Pa by a force of 200 N is 4 m².
What is force?Force is an external agent acting on a object to deform it or to change its state form motion or rest. Force is a vector quantity and it is characterised by its magnitude and direction. The unit of force is Newton (N).
Pressure is the force applied on unit area. Thus, as the force increases, pressure increases. Pressure can have the units in atm, pa, N/m² etc.
Pressure = Force / area.
Given that force = 200 N
pressure = 50 Pa = 50 N/m²
Therefore, area = force/pressure
= 200 N / 50 Pa
= 4 m²
Therefore, the area of the surface is 4 m².

A 95kg clock initially at rest on a horizontal floor requires a 560N horizontal force to set it in motion. After the clock is in motion, in horizontal force of 650N
Complete Question
A 95 kg clock initially at rest on a horizontal floor requires a 650 N horizontal force to set it in motion. After the clock is in motion, a horizontal force of 560 N keeps it moving with a constant velocity. Find the coefficient of static friction and the coefficient of kinetic friction.
Answer:
The value for static friction is [tex]\mu_s = 0.60[/tex]
The value for static friction is [tex]\mu_k = 0.70[/tex]
Explanation:
From the question we are told that
The mass of the clock is [tex]m = 95 \ kg[/tex]
The first horizontal force is [tex]F _s = 560 \ N[/tex]
The second horizontal force is [tex]F _k = 650 \ N[/tex]
Generally the static frictional force is equal to the first horizontal force
So
[tex]F _s = m * g * \mu_s[/tex]
=> [tex]560 = 95 * 9.8 * \mu_s[/tex]
=> [tex]\mu_s = 0.60[/tex]
Generally the kinetic frictional force is equal to the second horizontal force
So
[tex]F _k = m * g * \mu_k[/tex]
[tex]650 = 95 * 9.8 * \mu_k[/tex]
[tex]\mu_k = 0.70[/tex]

The gravitational force between two objects is 3600 N. What will be the gravitational force between the objects if the mass of each object is reduced to one third of its original mass
A. 400 N
B. 1200 N
C. 10,800 N
D. 32,400
Answer:
It will reduce by 9 times and become 400 N.
This question can be solved using the concepts of Newton's Law of Gravitation, and gravitational force.
The gravitational force between the two objects if the mass of each object is reduced to one-third of its original mass will be "A. 400 N".
According to Newton's Law of Gravitation the gravitational force between two objects is given as follows:
[tex]F = \frac{Gm_1m_2}{r^2}[/tex]---------- eqn (1)
where,
F = Gravitational force between objects = 3600 N
G = Universal gravitational constant
m₁ = mass of the first object
m₂ = mass of the second object
r = distance between the objects
Now, the masses have become one-third of the original value:
[tex]F'=\frac{G(\frac{m_1}{3})(\frac{m_2}{3})}{r^2}\\\\F' = \frac{1}{9}\frac{Gm_1m_2}{r^2}\\\\using\ eqn\ (1):\\\\F' = \frac{F}{9} = \frac{3600\ N}{9}\\\\[/tex]
F' = 400 N

A dog walks 8.0 meters due north and then 6.0 meters due east. Determine the magnitude of the dog's total displacement to the nearest tenths
Answer:
the magnitude of the dog's total displacement to the nearest tenths = 53.12°
Explanation:
Given that:
a dog walks 8.0m due to the north and 6.0 m due east.
We can determine the magnitude of the dog's total displacement by using the Pythagoras theorem.
Consider the north direction be the opposite and the east direction to be the adjacent, therefore the hypotenuse will be the dog's total displacement.
So, suppose hypotenuse is represented by a
the opposite represented by b, and the adjacent represented by c
Then;
a² = b² + c²
a² = 8² + 6²
a² = 64 + 46
a² = 100
a =[tex]\sqrt{100[/tex]
a = 10.0 m
However, the magnitude of the dog's total displacement is calculated by taking the tangent of the system.
tan θ = opposite / adjacent
tan θ = b/c
tan θ = 8/6
tan θ = 4/3
tan θ = 1.333
θ = tan⁻¹ (1.333)
θ = 53.12
the magnitude of the dog's total displacement to the nearest tenths = 53.12°

An object is projected with initial speed v0 from the edge of the roof of a building that has height H. The initial velocity of the object makes an angle α0 with the horizontal. Neglect air resistance. If α0 is 90∘, so that the object is thrown straight up (but misses the roof on the way down), what is the speed v of the object just before it strikes the ground?
Answer:
Explanation:
Initial velocity u = V₀ in upward direction so it will be negative
u = - V₀
Displacement s = H . It is downwards so it will be positive
Acceleration = g ( positive as it is also downwards )
Using the formula
v² = u² + 2 g s
v² = (- V₀ )² + 2 g H
= V₀² + 2 g H .
v = √ ( V₀² + 2 g H )

C. Obesity and diabetes
D. Obesity and heft
Answer: A. Overweight and obesity
Explanation:
Overweight and obesity are labeled for ranges of weight that are greater than what is generally considered healthy for a given height. Hence, option A is correct.
What are Overweight and obesity?Overweight and obesity are calculated by Body Mass Index (BMI). BMI is a person's weight in kilograms divided by the square of height in meters. The healthy adult human BMI ranges from 18.5 to 25.
If BMI is less than 18.5, it falls within the underweight range. If the BMI ranges from 25.0 to 29.9, it falls within the overweight range. If the BMI is greater than 30, it comes under the obesity range. A high BMI indicates high fatness.
Obesity and overweight are determined as an abnormal growth or excessive fat accumulation in the healthy range. It is caused by an energy imbalance between calories consumed and calories expended.
Obesity and Being overweight can cause certain diseases and health issues. It increases the risk of high blood pressure, heart disease, diabetes, and stroke.
It is important to maintain a healthy range BMI. Obesity and overweight are reduced by making the choice of healthier foods and regular physical activities like yoga and exercise.
