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 masslessstring passing over a massless, frictionless pulley. The system isreleased from rest.
a. draw a free- body diagram for each block showing all the appliedforces in the relative scale. Next to each diagram shot theexpected direction of acceleration.
b. What is the acceleration of the blocks?
c. What is the tension force in the rope?
d. how high will the 3.7 kg block move in the first 2.5 s?
e. find the speed of the 4.5 kg block at the end of 5seconds.
