After thecollision, the 5.8 kg block is observed to be traveling in theoriginal direction with a speed of 3.0 m/s. (a) What is thevelocity of the 2.9 kg block immediately after the collision? (b)By how much does the total kinetic energy of the system of twoblocks change because of the collision? (c) Suppose, instead, thatthe 5.8 kg block ends up with a speed of 4.8 m/s.
