Question

A rotating merry-go-round makes one complete revolution in 3.0 s . assume the wheel is moving with a constant angular velocity

Answer 1

angular speed of merry go round is given by

`w = (2\pi)/(T)`

here T = time period of one revolution

given that

T = 3 s

so we will have

`w = (2\pi)/(3) = 2.1 rad/s`

so speed of merry go round is 2.1 rad/s
