## Side View
1994B2. A track consists of a frictionless arc XY, which is a quarter-circle of radius R, and a rough horizontal section YZ. Block A of mass M is released from rest at point X, slides down the curved section of the track, and collides instantaneously and inelastically with identical block B at point Y . The two blocks move together to the right, sliding past point P , which is a distance L from point Y . The coefficient of kinetic friction between the blocks and the horizontal part of the track is μ Express your answers in terms of M,L,μ,R, and g .
a. Determine the speed of block A just before it hits block B.
b. Determine the speed of the combined blocks immediately after the collision.
c. Assuming that no energy is transferred to the track or to the air surrounding the blocks. Determine the amount of internal energy transferred in the collision
d. Determine the additional thermal energy that is generated as the blocks move from Y to P
