A hanging block A ( Ma = 15 kg) is connected by a light cable and a pulley wheel to a second block B ( Mb = 10 kg) situated at the bottom of a frictionless inclined plane with angle %u03B8 = 30o to the horizontal. If the hanging block is released from rest 5.0 m above the ground, find
a) the speed of the masses just before Ma touches the ground
b) the maximum distance that block Mb travels up along the inclined plane.
