Question

body is moving with a uniform speed of 5 metre per second in a circular path of radius 5 metre. The acceleration of the body is​

Answer 1

Explanation:

half revolution change in velocity

Δv=[5−(−5)]m/s=10m/s

Time taken to complete the half revolution is

t=

v

πr

π×5

=πs

Thus, average acceleration =

t

Δv

=
