physics

The masses of blocks A and B are 4.5 kg and 3.7 kg respectively. The blocks are initially at rest and are connected by a massless string passing over a massless, frictionless pulley. The system is released from rest.

a. What is the acceleration of the blocks?

b. What is the tension force in the rope?

c. how high will the 3.7 kg block move in the first 2.5 s?

d. find the speed of the 4.5 kg block at the end of 5 seconds.
