Car 1 has a mass of m1 = 65 multiplied by 10^3 kg and moves at a velocity of v01 = +0.82 m/s. Car 2, with a mass of m2 = 92 multiplied by 10^3 kg and a velocity of v02 = +1.1 m/s, overtakes car 1 and couples to it. Neglect the effects of friction in your answer.
(a) Determine the velocity of their center of mass before the collision
(b) Determine the velocity of their center of mass after the collision
(c) Should your answer in part (b) be less than, greater than, or equal to the common velocity vf of the two coupled cars after the collision?
