Question

This situation refers to the next three problems below. Two blocks are attached to a mossless cord and are hung around a frictionless pulley is shown. 4. First, assume that the pulley has no mass. a) Using free-body diagrams and Newton's 2nd Law, find the acceleration of each object and the tension in the rope. b) Find the speed of object 2 when it hits the ground. 5. Still assuming that the pulley has no moss: a) Use conservation of energy to find the speed with which object M2 hits the ground. b) How does this compare with your answer to part (b) in the lost problem? 6. Now assume that the pulley in the last problem is a cylindrical disk of mass 10.00 kg and radius 0.900 meters. a) What is the rotational inertia of the pulley? b) Use conservation of energy to find the speed with which object M2 hits the ground. c) How fast was the outside edge of the pulley moving when M2 hit the ground?

Explanation / Answer

sample answers for 4 question are a) acceleration of block = 6m/s^2 and speed at which it will hot the floor is 5.366 m/s
