A 2.84 kg block, traveling at a speed of 12.4 m/s, undergoes a perfectly inelastic
collision with a 3.68 kg block which starts at rest.
a) Find the final speed of each block.
b) Calculate how much energy was lost in the collision (final kinetic energy minus initial kinetic
energy). If you were unable to calculate the answer to part (a), assume the final velocity is 5.00 m/s.
c) How much energy would have been lost if the collision were elastic?
