Blocks a (5kg) and b (3kg) are released from rest on a 53 inclined surface and start sliding down the incline. before they released, the distance between the blocks is d. coefficient of kinetic friction between the block a and surface is 0.3. coefficient of kinetic friction between the block b and surface is 0.1. after 3s they are released, blocks collide and stuck together. 7.5p a) what is the initial distance, d, between the blocks? 7.5p b) what is the common velocity of the blocks after collision? 5p. c) how much mechanical energy is lost after collision? sin(53o)-0,8; cos(53°)-0.6 solution:
