- Homework Statement
- Question:
Trolley A, of mass 180 g, is moving at a velocity of 4 m/s towards trolley B which is stationary and has a mass of 120 g. Trolley A then collides with trolley B.
Calculate the speed of trolley B if:
i the collision is elastic (trolley A stops and trolley B moves off)
ii the collision is inelastic (the two trolleys join and move off together).
- Relevant Equations
- momentum = mass x velocity
So to cut to the chase, I missed my class' lesson on momentum - have tried to catch up, quite successfully but am baffled about this question. I know the conservation of momentum etc. but after trying for ages it's just not happening this question so any help would be much appreciated,
Oscar.
