A-Level momentum question
first post so here goes: this question isn't hard but i can't seem to get the answer i should have.
'a car of mass 1050kg runs into the back of car b which is stationary with mass 1200kg. car A was moving at 50mph immediately before impact. after impact, the vehicles are locked together'
calculate the speed at which the 2 vehicles move immediately after collision and the amount of kinetic energy lost in the collision. what has happened to this energy?
any help appreciated. thank you!
