Two blocks move along a linear path on a nearly frictionless air track. One block, of mass 0.104 kg, initially moves to the right at a speed of 5.20 m/s, while the second block, of mass 0.208 kg, is initially to the left of the first block and moving to the right at 7.30 m/s. Find the final velocities of the blocks, assuming the collision is elastic.
velocity of the 0.104 kg block?
velocity of the 0.208 kg block?
