A2 kg mass moving to the right makes an elastic head-on collision with a 4 kg mass moving to the left at 4 m/s. the 2 kg mass reverses direction after the collision and moves at 3 m/s. the 4 kg mass moves 1m/s to the left. what was the initial velocity of the 2 kg mass?

The experiment done in lab is repeated, using a ball that has unknown mass m. you plot your data in the form of f 2 versus m/l, with f in rev/s, m in kg, and l in m. your data falls close to a straight line that has slope 3.19 m/(kg · s2). use g = 9.80 m/s2 and calculate the mass m of the ball.
