please give answers and explain thank you.
A wheel on a game show is given an initial angular speed of 1.15rad/s. It comes to rest after rotating through 3/4 of a turn.
(a) Find the average torque exerted on the wheel given that it is adisk of radius 0.79 m and mass 6.4 kg.
? N·m
(b) If the mass of the wheel is halved and its radius is doubled,will the angle through which it rotates before coming to restincrease, decrease, or stay the same?
increase
decrease
stay the same
Explain. (Assume that the average torque is unchanged.)
