A bumper car with mass m, = 110 kg is moving to the right with a velocity of v1 = 4.8 m/s. A second bumper car with mass
m, = 2m, = 220 kg is at rest. The two have an elastic collision and the first bumper car rebounds backwards at a speed that
is 1/3 of its original speed (1.6 m/s). Assume the surface is frictionless.
1) What is the change in momentum of bumper car 1? (let the positive direction be to the right)
kg-m/s Submit
+
2) What is the change in momentum of BOTH bumper cars combined?
kg-m/s Submit
3) What is the change in momentum of bumper car 2?
