Two blocks are attached to opposite ends of a massless rope that goes over a massless, frictionless, stationary pulley. One of the blocks, with a mass of 4.5 kg accelerates downward at 34g.

Answer 1

What is the acceleration of the other block?

The acceleration of the other block is -34g. This is due to Newton's Third Law, which states that for every action, there is an equal and opposite reaction. Since the first block is accelerating downward at 34g, the other block must be accelerating upward at the same rate.
