The radius of a wheel is 0.740 m. A rope is wound around the outer rim of the wheel. The rope is pulled with a force of magnitude 5.00 N, unwinding the rope and making the wheel spin CCW about its central axis. Ignore the mass of the rope. How much rope unwinds while the wheel makes 1.00revolution?

___m How much work is done by the rope on the wheel during 1.00revolution?

__J

What is the torque on the wheel about its axis due to the rope? ___Nm

What is the angular displacement , in radians, of the wheel during 1.45 revolution? __rad

Which of the following equations describes rotational work?

• W=W=
• W=W=
• W=W=
• W=2W=2
