A mass m1 49 kg rests on a frictionless table and

Question

Solve the each part of given problem:

Problem: A mass m1 = 4.9 kg rests on a frictionless table and connected by a mass less string over a mass less pulley to another mass m2 = 4.6 kg which hangs freely from the string. When released, the hanging mass falls a distance d = 0.79 m.

Part A: How much work is done by gravity on the two block system?

Part B: How much work is done by the normal force on m1?

Part C: What is the final speed of the two blocks?

Part D: How much work is done by tension on m1?

Part E: What is the tension in the string as the block falls?

Part F: What is the NET work done on m2?

I need help to find the final speed of the two blocks.
