Figure 3.64 shows the position-time graphs of three car A, B and C. On the basis of the graphs, answer the following questions : Which car has the highest speed and which the lowest ?

A car runs on a circular track at a constant speed. The circular track has a radius of 100m. If the car takes 62.8 on each lap, its average speed is

The velocity- time graph of car moving on a straight track is given below. The car weight 1000kg. The distance travelled by the car during the whole motion is:

A car moving with a speed of 25 ms^(-1) takes a U-turn in 5 seconds, without changing its speed. The average acceleration during these 5 seconds is
