Work Done On A Rotating Wheel
Classical Mechanics
Level
2
A wheel is rotating at an angular speed of 20 rad/s. It is stopped to rest by applying a constant torque in 4 seconds. If the moment of inertia of the wheel about its axis is 0.20 kg m, then what is the magnitude of the work done by the torque in first two seconds?
