Question

A car runs at a constant speed on a circular track of radius 100 m , taking 62.8 seconds for every circular lap . then what is the average velocity and average speed for each circular lap/

Answer 1

a) Average velocity is zero because when it comes to the original point , then displacement will be zero.so average velocity will be zero.

b) Average speed is = total distance / time taken = 2πr / t = 2 X 3.14 X 100 / 62.8 = 10 m/s
