1) A pulley that is 6 cm in diameter and 1?2 cm thick (assume a cylinder) has a mass of 20 kg. At-tached to it is a 10 kg mass on a cable.

a) What is the angular acceleration of the pulley once the mass begins dropping?

b) If the mass drops 5 meters to the floor, how long does it take?

c) How long would it take if it were not attached to the cable or pulley (gravity only)?

d) What is its velocity once it strikes the floor?
