Block A with a mass of 9.0 kg moves along the x axis with a velocityof 6.0 m/s(in the positive x direction.) It suffers an ellastic collision with block B (15.0 kg), which initially has a velocity of -2.0 m/s(in the negative x direction). The blocks leave the collision along the x axis.
what is the initial kinetic energy of the system?
what is the initial momentum of the system?
what is the velocity of the blocks after the collision?

Block 1 (0.5 kg) travels with an initial velocity of [ 60i ] + [ 60j ] m/s and then collides with block 2 (0.5 kg) traveling with an initial velocity of [ -60i ] + [ -60j ] m/s. After the collision, block 1 has a final momentum of [ 0i ] + [ -20j ] kg*m/s. Assume that no external forces are present and therefore the momentum for the system of blocks is conserved.
