Question

A body starts performing uniform circular motion with 100 revolutions per minute.After how much minimum time it's average velocity will be zero?

Answer 1

Explanation:

body starts performing uniform circular motion such that it covers 100 rounds per min. Solution: The average velocity will be zero when the body completes one round. The body will take (60/100) s = 0.6s to complete one round. Hence the minimum time after which the average velocity will be zero = 0.5s.

Answer 2

Answer:-

.After Completing 1 round its average velocity will become zero as displacement will be zero.

$\longarrow \sf \: time \: spent \: in \: one \: round \: = \: \frac{1 \: min}{100 \: revolution} \: = \: \frac{60s}{100} \: = \: 0.6s$
