Homework Help: Physics

Two blocks are positioned as shown below. block A has a mass of 15 kg and hangs on one end of a cable that passes over a frictionless and massless pulley. The other end of the pulley is attatched to block B which has a mass of 10 kg. Block B rests on an incline which has an angle of inclination of 30 degrees.

Assuming the system is released from rest, what will be the acceleration of block B?

Write equations of motion for Masses A and B separately, with the cable tension T acting on both.

They both accelerate at the same rate, a.

Solve the two equations in two unknowns.
