6 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 I from point Y The coefficient of kinetic friction between the blocks and the horizontal part of the track is u Express your answers in terms of M 0 R and g X M Hk 0 Block A M Y Block B Hk l Side View 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 Determine the amount of kinetic energy lost due to the collision d The specific heat of the material used to make the blocks is c Determine the temperature rise that results from the collision in terms of c and the other given quantities Assume that no energy is transferred to the track or to the air surrounding the blocks e Determine the additional thermal energy that is generated as the blocks
