Question

an object is travelling in a circular path of radius 21 m ,it covers the circular path in 15 seconds ,find it's velocity​

Answer 1

Answer:

Explanation:

so the radius of the the circular path is 21m and the object completes its one round in 15 second so

v(velocity)= 2πr/t

v = (2×3.14×21)/15

v = 130.2/15

v = 8.68m/s
