  1. Speed amplifier. Block 1 of mass m1 slides along an x axis on a frictionless floor with a speed of Then it undergoes a one-dimensional elastic collision with stationary block 2 of mass m2 = 0.500m1. Next, block 2 undergoes a onedimensional elastic collision with stationary block 3 of mass m3 = 0.500m2. (a) What then is the speed of block 3? (b) Are the kinetic energy, and the momentum of block 3 greater than, less than, or the same as the initial values for block 1?

Block 1, with mass m1 and speed 5.4 m/s, slides along an x axis on a frictionless floor and then undergoes a one-dimensional elastic collision with stationary block 2, with mass m2 = 0.65m1. The two blocks then slide into a region where the coefficient of kinetic friction is 0.56; there they stop. How far into that region do (a) block 1 and (b) block 2 slide?

block 1 of mass m1 slides from rest along a frictionless ramp from an unknown height h and then collides with stationary block 2, which has mass m2 = 3m1 . The collision is an elastic one. After the collision, block 2 slides into a friction-filled region where the coefficient of kinetic friction is 0.5 and comes to a stop through a distance d = 10 m in that region. What is the height h?
