A 3.0 kg block is traveling in the -x direction at 5.0 m/s, and a1.0 kg block is traveling in the +x direction at 3.0 m/s.
a.) Find the velocity VCM of the center of mass.
b.) Subtract VCM from the velocity of each block to find the velocity of each block in the center-of-mass reference frame.
c.) After they make a head-on elastic collision, the velocity ofeach block is reversed (in the center-of-mass frame). Findthe velocity of each block in the center-of-mass frame after thecollision.
d.) Transform back into the original frame by adding VCM to the velocity of each block.
e.) Check your result by finding the initial and final kineticenergies of the blocks in the original frame and comparingthem.
