Question
(4%) Problem 3: Car B is following Car A and has a greater speed than Car A. The two cars are moving in a straight line and in the same direction, and have the same mass. In situation one, Car A is traveling at 10 mph and Car B at 20 mph. In situation two, Car A is traveling at 30 mph and Car B at 40 mph. Assuming a perfectly inelastic collision in which the cars stick together after the collision, which of the following will be true? The force of the collision in the two situations will be equal. Situation two will cause the greater force of collision. Situation one will cause the greater force of collision.

Hints remaining:- Feedback: 4%-deduction per feedback.Explanation / Answer
In situation one, common velocity when both will move together will be (10+20)/2 = 15 mph
In situation two, common velocity when both will move together will be (30+40)/2 = 35 mph
Change in momentum in both the situations will be equal for both the cars so The force of the collision in the two situations will be equal.
