Problem
Two cars, A and B, travel counter-clockwise around a perfectly circular racing track of radius 50m. Car A maintains a constant speed of 10m/s, while car B maintains a constant speed of 15m/s. Answer the following:
(i) Determine the time period of one complete revolution for each car.
(ii) Which car requires a greater force directed towards the centre of the track to maintain its motion? Justify your answer qualitatively.
(iii) Do either of the cars possess uniform velocity during their motion? State the reason for your answer.
