1. The problem statement, all variables and given/known data A trolley of mass 2kg, travelling at 3m/s, collides with a stationary 1kg trolley. If the trolleys stick together, calculate: a) the total momentum before thecollision b) the speed of the two trolleys arter th collision 2. Relevant equations momentum = mass x velocity momentum before collision or explosion = momentum after collision or explosion a collision is where equal forces act in opposite directions. An explosion is when objects 3. The attempt at a solution how do i get B?
