Question 53

A student investigates how the starting height of a model car rolling down a ramp affects its speed at the bottom.

Key data from the experiment is recorded in the table below:

Release height / $m\text{m}$	Average speed / $ms−1\text{ms}^{-1}$
0.05	0.40
0.10	0.57
0.15	0.69
0.20	0.80
0.25	0.89
0.30	0.98

The model car has a mass of 750 g.

Calculate the kinetic energy of the car when it is released from a starting height of 0.20 m.
