Question

The Atwood machine shown in figure below consists of a mass M=500.g and a mass m=300.g connected by a light string that passes over a pulley in the shape of a disk of mass 750.g and radius r=10.0cm. The string does not slip on the edge of the pulley, which turns without friction about its center. Find the tensions in the string segments and the acceleration a of the system. Use the conservation of energy to calculate the velocity of the 500.g mass after it has fallen 1.00m if system starts from rest.

Explanation / Answer

the height descended by a will be = height ascended by b

velocity of both blocks are equal and also equal to the tangential velocity of the pulley..

please rate me atleast 4 stars so that i will get full points
