Collisions

Momentum is a vector quantity.In a collision, momentum is always conserved. The total initial momentum is equal to the total final momentum.The objects may stick together and move forward together, or one object could transfer momentum to the other. The loss of momentum of one object is the gain of momentum of the other object.

m = mass, u = initial velocity, v = final velocity.
Total initial momentum =(600 × 25) + (2400 × -10)
