Practice Problem: Two-Dimensional Two-Body Problem

The video tutorial explains a physics problem involving a pulley system with two blocks. Block A rests on a frictionless ramp, and Block B hangs vertically. The tutorial explores what happens when the blocks are released, using Newton's laws, tension, and trigonometry. It identifies forces acting on each block, calculates gravitational forces, and determines the net force causing Block A to slide down the ramp, pulling Block B upwards.

What is the significance of the angle of the ramp in determining the forces acting on block A?

Calculate the net force acting on block A and explain its effect on the motion of the blocks.
