A race car is accelerating at 5m/s and then speeds up to a final velocity of 12 m/s if the race car driver finished this let of the race in 6 seconds what was the car's acceleration
Answer:
the acceleration of the car is 1.167 m/s²
Explanation:
Given;
initial velocity of the race car, u = 5 m/s
final velocity of the race car, v = 12 m/s
time to finish the race, t = 6 s
The acceleration of the car is calculated as;
a = (v - u) / t
a = (12 - 5) / (6)
a = 1.167 m/s²
Therefore, the acceleration of the car is 1.167 m/s²
Answer:
1.167 m/s^2
Explanation:
Given that a race car is accelerating at 5m/s and then speeds up to a final velocity of 12 m/s if the race car driver finished this let of the race in 6 seconds what was the car's acceleration ?
From the question, the following parameters are given
Initial velocity U = 5 m/s
Final velocity V = 12 m/s
Time t = 6 s
According to the definition of acceleration:
Acceleration = change in velocity per time taken.
I.e
Acceleration =( V - U)/ t
Acceleration =( 12 - 5 )/6
Acceleration = 7/6
Acceleration = 1.167 m/s^2
Therefore, acceleration is 1.167 m/s^2

What is the mass of an object that requires 100N of force in order to accelerate 10m/s2
Explanation:
Hey there!
Given;
Force (f) = 100 N
Acceleration (a) = 10m/s^2.
Mass (m)=?
We have;
Force = mass * acceleration.
So,
100 = m * 10
Or, 100 = 10m
Or, m= 100/10
Therefore, mass is 10kg.

Answer:
A car engine has more power than a horse because a car engine does the same amount of work in time. Yasmin and Raj each had 10 boxes of equal weight to stack next to each other on the same shelf, at the same height and in the same arrangement. Yasmin completed the task in 2 minutes, while Raj took 3 minutes to stack his boxes. Raj applied less power than Yasmin because his stacking took more time to do the same amount of work.
Explanation:
A car engine has more power than a horse because a car engine does the same amount of work in less time. Raj applied less power than Yasmin because his stacking took more time to do the same amount of work.
What is power?The quantity of energy moved or converted per unit of time is known as power in physics. The watt, or one joule per second, is the unit of power in the International System of Units. Power is also referred to as activity in ancient writings. A scalar quantity is power.
Energy divided by time represents the dimension of power. The watt (W), which equates to one joule per second, is the unit of power in the International System of Units (SI).
Another popular unit of measurement is horsepower (hp), which is equivalent to a horse's power; one mechanical horsepower is equal to around 745.7 watts.

The change in momentum for an object is equal to
Answer:
We conclude that the change in momentum of a body is equal to the impulse experienced by a body.
Explanation:
Considering the equation
F • t = m • Δ v
Here,
m • Δ v is basically a change in momentum of a body which is equal to the mass of the object multiplied by the change in its velocity.
Also,
F • t is called the impulse of the object.In the formula, it is clear that the impulse experienced by a body during the collision is basically a change in the momentum of the body.
In other words, the change in momentum of a body is equal to the impulse experienced by a body.
Therefore, we conclude that the change in momentum of a body is equal to the impulse experienced by a body.
An oil tank has a base of area 2.5 m2 and is filled with oil to a depth of 1.2 m. The density of the
oil is 800 kg/m3. What is the force exerted on the base of the tank due to the oil?
A. 960N
B. 2400N
C. 9600N
D. 24 000N
Answer:
D. F = 24000[N]

To be able to calculate the force we must first find the pressure at the bottom of the tank. By means of the following equation:
[tex]P=Ro*g*h[/tex]
where:
Ro = density of the liquid = 800 [kg/m³]
g = gravity acceleration = 9.81 [m/s²]
h = elevation = 1.2 [m]
[tex]P=800*9.81*1.2\\P=9417.6[Pa][/tex]

Your 1500kg car is stuck behind a truck traveling 27 m/s. To pass it, you speed up to 34 m/s in
6.0 s. What power is required to do this?
Answer:
P = 53375[W]
Explanation:
First, we must use the following equation of kinematics, which allows us to calculate the acceleration value.
[tex]v_{f}=v_{o}+a*t[/tex]
where:
Vf = final velocity = 34 [m/s]
Vo = initial velocity = 27 [m/s]
a = acceleration [m/s²]
t = time = 6 [s]
Now replacing:
[tex]34=27+a*6\\a=1.167[m/s^{2} ][/tex]
Now we must use Newton's second law, which tells us that the sum of forces is equal to the product of mass by acceleration. In this way, we have the following equation.
ΣF =m*a
where:
F = force [N]
m = mass = 1500 [kg]
a = acceleration = 1.167 [m/s²]
[tex]F=1500*1.167\\F=1750[N][/tex]
Power is defined as the product of force by speed. But we have two speeds, the initial and the final. We must use the average speed to be able to estimate the power needed.
[tex]V_{average}=\frac{34+27}{2} =30.5[m/s][/tex]
And the power:
[tex]P=F*V_{average}\\P=1750*30.5\\P=53375[W][/tex]

3. The number of revolutions made by a tire traveling over a fixed distance varies inversely to the radius of the
tire. A 12-inch radius tire makes 100 revolutions to travel a certain distance. How many revolutions would a
16-inch radius tire require to travel the same distance?
Answer:
Most people when asked, “What is the equation of a line?”, will answer, “y = mx + b”. This is the
equation of a line in what is called slope-intercept form where “m” is the slope and “b” is the yintercept. So, how do you find the equation of a line? There are several different ways that you can find
the equation of a line. I find the equation of a line everytime by following the same three steps:
Step 1: Find the slope of the line.
Step 2: Use the slope to find the y-intercept.
Step 3: Use steps 1 and 2 to write the answer.
I will explain these steps by looking a several examples. Please understand that there are often several
different ways to complete each math problem, but I have found through the years that students are most
successful when the do problems the same way each and every time they attempt the problem. If you
know a different way to find the answer that is great, but I am going to show how to do the problem one
way and use the same technique everytime I see this problem.
Explanation:
The ratio of number of revolution to the radius of the tire will be constant since the distance is constant. 16 - inch radius tire will require 75 revolutions to travel the same distance.
CIRCULAR MOTIONWhen all points in a body move in concentric circles is known as rotational or circular motion. Below are few facts about circular motion.
Speed is constantVelocity keeps changingAcceleration acts toward the center.Given that the number of revolutions N made by a tire traveling over a fixed distance D varies inversely to the radius r of the tire. That is
N [tex]\alpha[/tex] 1/r
N = K/r
K = Nr
Where K = Proportionality constant
If a 12-inch radius tire makes 100 revolutions to travel a certain distance, Then,
K = 100 x 12
K = 1200 rev inches
How many revolutions would a 16-inch radius tire require to travel the same distance?
by applying the same formula, let us substitute r for 16 inches and 1200 for K
K = Nr
1200 = N x 16
N = 1200/16
N = 75 revolutions
Therefore, 16 - inch radius tire will require 75 revolutions to travel the same distance.
