Homework Help: AP physics

Posted by Kristen on Sunday, January 27, 2008 at 9:34am.

On Block has a mass M=500 g, the other has mass m=460 g, they are hooked to a string and is on a pulley will one mass on either side, the pulley, which is mounted in horizontal frictionless bearings, has a radius of 5 cm. When released from rest, the heavier block falls 81.5 cam in 2.51 s (withouth the cord slipping on the pulley).

What is the magnitude of the blocks acceleration?

What is the tension in the part of the cord that supports the heavier block?

What is the tension in the part of the cord that supports the lighter block?

What is the magnitude of the pulleys angular acceleration in rad/s squared?

What is its rotational inertia?
