A mass m1 = 3.9 kg rests on a frictionless table and connected by a massless string over a massless pulley to another mass m2 = 5.7 kg which hangs freely from the string. When released, the hanging mass falls a distance d = 0.8 m.
1) How much work is done by gravity on the two block system?
J
2) How much work is done by the normal force on m1?
3) What is the final speed of the two blocks?
m/s
4) How much work is done by tension on m1?
5) What is the tension in the string as the block falls?
N
6) What is the NET work done on m2?
