Question

Physics
A body is moving with constant speed of 5m/s along a circular path of radius 5 cm when it reaches the diametrically opposite point the magnitude of average speed is?

Answer 1

Answer:

Answer will be

10/π ms-²

Answer 2

Explanation:

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
