Question

A mass on a

string is swung in a circle of radius 1.0m
at a speed of 5.0mls. What is the period of
revolution?​

Answer 1

S = 2 * pi * 1 m = 6.28 m = distance traveled

V = S / T or T = S / V = 6.28 m / 5 m/s = 1.26 sec

This will be the time for 1 revolution or the period of the motion.
