A car runs at a constant speed on a circular track of radius 100m, taking 62.8s for every circular loop. The average velocity and average speed for each circular loop respectively is:

Options

A. 0,10 m/s
B. 10 m/s , 10 m/s
C. 10 m/s , 0
D. 0 ,0

Answer

A

Explanation

Distance covered in one circular loop = `2pir`
=2 x 3.14 x 100 = 628 m
Speed =`628/62.8`=10 m/sec
Displacement in one circular loop =0
Velocity = `0/"time"`=0
