Question

Based on Speed, Velocity and Acceleration
An athlete covers a circular path of radius 70 m in 55 s
and returns to the starting point. Find the magnitude of
his average speed and average velocity. If he completes
the last 40 m of the path at the same rate in 4 s, find the
value of instantaneous speed and velocity in that inter-
val of time. [8 m·s-1,0; 10 m·s-1, 10 m.s​
