Q1. Chuck Norris's razor blade has an output force of 2500 lbs is used to shear his burley face. The shaving blade has the 0.35 inch thick blade with a 55 degree slope.
Q2. A thin light string is wrapped around the outer rim of a uniform hollow cylinder of mass 4.95 having inner and outer radii. The cylinder is after that released from rest.
How far should the cylinder fall before its center is moving at 6.56?
If you just dropped this cylinder without any string, how fast will its center be moving when it had fallen the distance in part A?
Why do you get two different answers? The cylinder falls the similar distance in both cases.
