A 1000-kg car moving at 30m/s due north collides completely elastically with a 1250-kg truck heading north of east. After the collision the truck is moving due north and the car is moving due east. Find the initial speed of the truck.
I think the answer is 34m/s and we have to break it up into x and y component and equate them but please tell me the theory behind it. Thanks

A 1425 kg truck driving at 13.0 m/s collides elastically with a stationary 1175 kg car. If the car is traveling 14.25 m/s just after the collision, what is the velocity of the truck immediately after the collision? Assume that this is a perfectly elastic collision. Round your answer to the hundredths place. Final velocity of the truck = m/s

A 1200·kg car traveling with a velocity of 12·m/s north collides head-on with a 2400·kg truck traveling with a velocity of 8·m/s south. Immediately after the collision, the velocity of the car is 4·m/s south. Take north as the positive direction (a) What is the velocity of the truck immediately after the collision? (b) What impluse is delivered to the car by the truck? (c) What impluse is delivered to the truck by the car?
