A car with a mass of 1.1 × 103 kilograms hits a stationary truck with a mass of 2.3 × 103 kilograms from the rear end. The initial velocity of the car is +22.0 meters/second. After the collision the velocity of the car is -11.0 meters/second. What is the velocity of the truck after this elastic collision? @mjdennis

What do you know so far about elastic collisions?  Got a starting place?

I have to go for the day. My reference for elastic collisions is this: http://hyperphysics.phy-astr.gsu.edu/hbase/elacol2.html Maybe that will help. @welshfella maybe you could help @school.stusy.guy123 out?
