Two carts having the same mass travel towards each other, each with a speed of 1m/s relative to teh surface. The carts collide head on and are reported to rebound after teh collision, each with a speed of 2m/s relative to teh surface. Which of the following assesments of this report is correct?
a) Momentum was not conserved therefore the report is false
b) If potential energy was released to the carts during the collision, the report could be true
c) If teh carts had different masses, the report could be true
d) If the surface was inclined the report could be true
e) If there was no friction between the carts and the surface the report could be true
I feel it'll be either b) or d) but arent they essentially talking about the same idea? If they were on an incline, the potential energy will be released
