The engine of an unpowered toy train is rolling at a constant speed on a level track, as shown in Fig. 3.1. The engine collides with a stationary toy truck, and joins with it. moving engine stationary truck track Fig. 3.1 Before the collision, the toy engine is travelling at 0.32 m/ s. The mass of the engine is 0.50 kg. (a) Calculate the momentum of the toy engine before the collision. (b) The mass of the truck is 0.30kg. Using the principle of conservation of momentum, calculate the speed of the joined engine and truck immediately after the collision.

How to calculate problems involving the momentum of an object,mass and velocity?
Indicate the given, diagram, FBD, and the solution with no shortcuts. 1) A numbered pool ball with a mass of 0.03 slug collided with a cue ball of 0.02 slug at rest on a frictionless pool board.The numbered pool ball has an initial velocity of 160 in/s directed horizontally to the right and a final velocity of 80 in/s in an unknown direction. Find a) the final speed of the cue ball and b) the angles of direction θ & Φ of the numbered pool and the cue balls after the collision.
answer the speed of the defendant's car, in m/s. Plaintiff's speed: 15.0 m/s Skidmark angle: 58o Both car masses are the same. The plaintiff's car was going eastbound, while the defendant's car was going northbound. They collided and skidded together. The angle is the angle from the east direction.
