A wheel stars at rest, has a radius of 0.1m and has a moment of inertia I=10kg*m^2. A constant torque of 3 N*m is applied to the wheel to cause counter-clockwise angular acceleration
1) what will the angular velocity of the wheel be when the angular displacement is 20*pi radians?
2) what will the tangentail speed of a point on the outer edge of the wheel be when the angular velocirt of the wheel is your answer to part 2?
3) how long will it take for the wheel to achieve the angular velocity in part 2
4) if the torque is removed at the time you found in pert 3, what magnitude of torque would you need to apply to the wheel in order to stop the wheel in 3.07s?
