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?
