A 2.7-kg block is traveling to the right (the +x direction) at 5.1 m/s, and a second 2.7-kg block is traveling to the left at 1.8 m/s.
(a) Find the total kinetic energy of the two blocks.
(b) Find the velocity of the center of mass of the two block system.
(c) Find the velocity of each block relative to the center of mass.
(d) Find the kinetic energy of the blocks relative to the center of mass.
