Question

Scenario :
A truck has a mass of 2000kg and is moving at 50m/s and collides with another truck that has a mass of 2000kg moving at a speed of -20m/s.

1)Is this a sticky or springy collision?
2)What is the total momentum after the collision?
3)If both trucks stick together and begin to move off after this Collison , at what speed will they move off at?

Answer 1

It probably will be inelastic.
total momentum after=2000*50+2000*(-20)

3) momentum after=(4000)V=2000*30
V=15m/s
