Okay I have been working on this problem forever and I don't know what else to try. Can anyone help me?.... A 0.005-kg block is released from rest at the top of a frictionless track 2.50 m above the top of a table. It then collides elastically with a 1.00-kg object that is initially at rest on the table. (a) Determine the velocities of the two objects just after the collision. (b) How high up the track does the 0.500-kg object travel back after the collision? (c) How far away from the bottom of the table does the 1.00-kg object land, given that the table is 2.00 m hight? (d) How far away from the bottom of the table does the 0.500-kg object eventually land?
