A turntable rotates at 100 rev/min. Calculate the angular speed in rad/s and in degree/s.

A turntable rotates at 100 rev/min. Calculate the angular speed in rad/s and in degree/s.

A man of mass $100kg$ stands at the rim of a turntable of radius $2m$ and moment of inertia $4000kg{m}^2$ mounted on a vertical frictionless shaft at its center. The whole system is initially at rest. The man now walks along the outer edge if the turntable(anticlockwise) with a velocity of $1m/s$ relative to earth. With what angular velocity and in what direction does the turntable rotate?

A gramophone turntable rotating at an angular velocity of $3rad/s$ stops after one revolution. Find the angular retardation. (in $rad/s^2$)

A fly wheel rotating at 600 rev/min is brought under uniform deceleration and stopped after 2 min, then what is the angular deceleration in rad/$se{c}^2$?

A merry- go- round ( diameter 4.0 m ) starts from rest and uniformly accelerates until it rotates at 0.8 rev/min. This occurs in 11s. Once it has reached this rate , it rotates at 0.8 rev/min uniformly . Determine the angular acceleration
