Question

A car runs at constant speed on a circular track of
radius 100 m taking 62.8 s on each lap. What is the
average speed and average velocity on each
complete lap?
(A) velocity 10 m/s speed 10 m/s
(B) velocity zero, speed 10 m/s
(C) velocity zero, speed zero
(D) velocity 10 m/s, speed zero
​

Answer 1

u will get the circumference by

2 ×pi × 100

=62.8 ×10 m
