Ok, so m1 = 5,000 kg moving 40 m/s to the right and m2 = 3,000 Kg and moving 40 m/s to the left.
a. How fast are the two masses moving after the collision? Pay no attention to the
15 mph after picture.
b. If the brakes lock and the coefficient of friction is 0.4, how far will the truck-car.
slide?
c. Explain the change in momentum of the truck and the car relative to each other
(i. e. the truck experienced a greater change in momentum than the car because
...). Hint: there are only three choices, the truck experiences a greater change in
momentum, the car experiences a greater change in momentum or the car and
truck experience the same change in momentum.
