1 answer:
The motion diagram for A-E is attached.
F) The drawings will change to reflect how the spacings of the respective positions are changing more irregularly.
<h3>What are motion diagrams?</h3>A motion diagram is an image that represents the position of an object at various relatively spaced time intervals.
The art of using motion diagrams is called kinematics. it is useful for detecting the unknown speed of objects. For example, the movement of a rocket from earth to space, the movement of a ship over the water.

Given:
Mass (m) = 1200 kg
Distance (s) = 100 m
Time (t) = 10 seconds
Now,
=
= 10 m/s
<span><u>Note that this one is the final velocity.</u></span><u />
We also know that,
initial velocity (u) = 0 m/s .......<span> because the car starts from rest.
</span>Now,
=
=
= 1 m/s²
Now,
Force (F) = mass (m) * acceleration (a)
= 1200 kg * 1 m/s²
= 1200 kg.m/s²
= 1200 N
Now,
Work Done (W) = Force (F) * displacement (s) ....<span>note that displacement is same as distance.
</span><span> = 1200 N * 100 m
</span> = 120000 N.m
= 120000 J
Now,
Power (P) =
=
= 12000 J/s
= 12000 watt
SO,
A) The acceleration of the car is 1 m/s².
B) 1200 Newton (N) force must have acted on the car.
C) The velocity of the car after 10 seconds is 10 m/s.
D) 120000 Joule (J) work was done on the car.
E) The engine produced a minimum power of 12000 watt.
