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.

    A 1-kg pellet travels with velocity 160 m/s to the right when it collides with a 39-kg hanging mass which is initially at rest. After the collision, the pellet remains lodged in the hanging mass, i.e., it is a completely inelastic collision. The hanging mass (+pellet) then swings upward and reaches a maximum height hmax before swinging downward again. Assume that no external forces are present and therefore the momentum of the system is conserved. What is the velocity vf...
