Question

A particler moves on a circle of radius 7m and complete 3/4 rotation in 1.4 second. Find the speed and velocity of particles

Answer 1

Radius = 7m
Distance needed to cover to complete 1 revolution= 2×(22/7)(7)
=44m
Distance covered = 44×(3/4)
=33m
Time taken = 1.4 s
Speed = distance/time
=33/1.4
=23.57 m/s
And beacuse it's moving on a circular path it's velocity would be 0.
