Question

Find the time period of the body if body travel in a circular path in 30m/s and given radius of circular path is 7m

Answer 1

GIVEN -speed=30m/s

distance=7m

so we know that, speed=distance/time

so here body is travelling in circular path so its distance will be 2 pie r

so , time =distance /speed

distance=2 pie r

distance =2×22/7×7

we get distance=44m

t=44/30

time =1.46s
