Science

A rod of length L=1.80m is mounted to a wheel (solid cylinder) of radius R=8.00cm. A massless rope is wound on the wheel, and then connects to a block of mass m=0.250kg. The mass is released from rest and allowed to fall.
1. Find the tension in the rope.
2. How long does it take for the mass to fall 0.50m?
