A block of mass m, 150 kg is at rest on a very long frictionless table, one end of which is terminated in a wall. Another block of mass my is placed between the first block and the wall, and set in motion towards m, with constant speed Uz. Assuming that all collisions are completely elastic, find the value of my for which both blocks move with the same velocity after m, has collided once with m, and once with the wall. (The wall has effectively infinite mass.)
1) 10 kg 2) 20 kg 3) 40 kg 4) 50 kg
