Question

a cycle is moving on a circular path such that it covers 30 degrees in 30 seconds calculate time period for cycle frequency of cycle​

Answer 1

When the particle completes half revolution change in velocity

Δv=[5−(−5)]m/s=10m/s

Time taken to complete the half revolution is

t=

v

πr

=

5

π×5

=πs

Thus, average acceleration =

t

Δv

=

π

10

m/s
