Answer:
The answer is 0.23 m/s²Explanation:
The acceleration of an object given it's mass and the force acting on it can be found by using the formula
[tex]a = \frac{f}{m} \\ [/tex]
f is the force
m is the mass
From the question we have
[tex]a = \frac{3}{13} \\ = 0.230769...[/tex]
We have the final answer as
0.23 m/s²Hope this helps you
Write the benefit of reduced load distance in a lever?
Explanation:
A machine is a device that does work. Most machines consist of a number of elements, such as gears and ball bearings, that work together in a complex way. Nonetheless, no matter how complex they are, all machines are based in some way on six types of simple machines. These six types of machines are the lever, the wheel and axle, the pulley, the inclined plane, the wedge, and the screw.

Lorries sometimes have a curved metal sheet fitted on top of the cab. Explain why as fully as you can ?.
Explanation:
A vehicle frame, also known as its chassis, is the main supporting structure of a motor vehicle to which all other components are attached, comparable to the skeleton of an organism.
Until the 1930s, virtually every car had a structural frame separate from its body. This construction design is known as body-on-frame. Over time, nearly all passenger cars have migrated to unibody construction, meaning their chassis and bodywork have been integrated into one another.
Nearly all trucks, buses, and most pickups continue to use a separate frame as their chassis

You and Tim, who is larger than you, are outside with a wagon. Tim (the bigger person) gets in the wagon and you (the smaller one) pull it. As you pull it, you accelerate until you reach a comfortable velocity. Then you stop and switch places with Tim. Tim now pulls you in the wagon, accelerating from a stop to a comfortable velocity. Now, Tim may be bigger than you, but you have been working out and are just as strong as Tim, so the force that Tim uses to pull the wagon is the same force that you used. You both pull with the exact same amount of force. Who was riding in the wagon when it had the greatest acceleration during start up? Why? Use Newton’s second law to explain. Now Sara comes along, and she is the exact same size as you. However, she is even stronger than you! When she pulls you in the wagon, she pulls with a greater force than when you pull her. Now who is in the wagon when it has the greatest acceleration? Explain, using Newton’s second law.
Answer:
It would be you.
Explanation:
You are smaller than Tim, so although you're pulling each other with the same force, you are smaller, so the wagon would accelerate faster when you are in it. Newton's second law depends on force and mass. Tim and you, respectively.
It would be you.

The Jamaican bobsled team was moving at a velocity of 50 m/s, then they hit the brakes on their sled to decelerate at a uniform rate of -5 m/s2 . How long does it take to stop if it travels 250 m before coming to rest?
Answer:
The time it took the bobsled to come to rest is 10 s.
Explanation:
Given;
initial velocity of the bobsled, u = 50 m/s
deceleration of the bobsled, a = - 5 m/s²
distance traveled, s = 250 m
Apply the following kinematic equation to determine the time of motion of the bobsled;
s = ut + ¹/₂at²
250 = 50t + ¹/₂(-5)t²
250 = 50t - ⁵/₂t²
500 = 100t - 5t²
100 = 20t -t²
t² - 20t + 100 = 0
t² -10t - 10t + 100 = 0
t (t - 10) - 10(t - 10) = 0
(t - 10)(t - 10) = 0
t = 10 s
Therefore, the time it took the bobsled to come to rest is 10 s.

State the relation between the joule and kilocalories.
Explanation:
1 Kilocalories = 4,184 Joules
Answer:
The relationship between calorie and joule are proportionate. Which implies, the calorie is directly proportional to the joule. That means-
When the value in terms of calorie increases, its corresponding value in joules also increases at a rate of 4.2.
When the value in terms of calorie decreases, its corresponding value in joules also decreases at a rate of 4.2.

A student tries to measure the period of a pendulum that is already swinging
left and right. At the moment when the pendulum is fully to the left, she
counts 'One' and starts a stopwatch. She counts successive swings each time
that the pendulum returns to the left. When she counts ‘Ten' she stops the
stopwatch, and sees that it reads 12.0 s.
a. What was her mistake?
______________________________________________________________
b. What is the period of swing of this pendulum?
______________________________________________________________
c. In this particular experiment, explain the likely effect of her reaction time
on her answer.
Answer:
a. The student's mistake was that the student did not swing the pendulum and start the watch at the same time.
b. 1.2 s per swing.
c. The likely effect of her reaction time is that they will should subtract two seconds off the time.
Explanation:
The pupil made the error of not simultaneously starting the watch and swinging the pendulum.
What is pendulum?Pendulum is defined as a body that is suspended from a fixed point and moves back and forth while being pulled by gravity. The pendulum is used to gauge the gravitational pull because the force of gravity causes it to swing back toward its average position. A pendulum's time period can be used to tell the time because it is constant.
The swing of the pendulum is 1.2 sec. per swing. They should take two seconds off the timing due to her presumably slow reaction time. A pendulum's total time should be divided by the quantity of oscillations in order to determine its time period. When compared to a pendulum with a shorter string, the one back and forth cycle of a longer-stringed pendulum requires more time to complete.
Thus, the pupil made the error of not simultaneously starting the watch and swinging the pendulum.

A large truck of mass 5000 kg is travelling at 5.0 m/s.

What is the speed of the motorbike?
A 25 m/s
B 10 m/s
C 125m/s
D 2.5 m/s
Answer:
A - 25m/s
Explanation:
The velocity of the motorbike will be 25 m/s in order to ensure that the truck and the motor bike have the same kinetic energy.
What is Kinetic Energy?The kinetic energy of the body is by the virtue of its motion.
Given is a large truck of mass 5000 kg which is travelling at 5.0 m/s and a motorbike that has a mass of 200 kg. Both the truck and the motor bike have the same kinetic energy.
The Kinetic energy of the truck will be -
E[T] = 1/2 mv² = 1/2 x 5000 x 25 = 2500 x 25 = 62500 joules
Then Kinetic energy of the motorbike will be -
E[M] = 1/2 x 200 x v²
E[M] = 100v² joules
Now-
E[T] = E[M]
100v² = 62500
v² = 625
v = 25 m/s
Therefore, the velocity of the motorbike will be 25 m/s in order to ensure that the truck and the motor bike have the same kinetic energy.
