Question

a particle moves on circular path of radius 5m with constant speed 5m/s. find the magnitude of its average acceleration when it completes half circle. please help and i will mark the best as brainliest​

Answer 1

Answer:

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
