Homework Help: physics

Posted by aok on Wednesday, November 10, 2010 at 7:42pm.

A delivery truck with a mass of 1700 kg is stopped in the street w/o its brakes on, when a small car hits it from behind. The car has a mass of 650 kg, and is traveling at 3.7m/s immediately before it hits the truck. Both the car and the truck have good bumpers, so assume the collision is elastic.

Find the final velocity of the two vehicles. Consider the direction that the car was originally traveling to be the forward direction

Detailed solutions, with step by step instructions are greatly appreciated. THANK YOU!
