Question

An inelastic collision occurs between a large truck and smaller sedan. Calculate the final velocity of the objects and explain the direction they will be traveling with the following data from before the collision: Small sedan mass = 1300 kg initial velocity = 20 m/s Truck mass = 7100 kg Initial Velocity 15 m/s

Answer 1

momentum is conserved

(7100 * 15) - (1300 * 20) = (7100 + 1300) * v
... in the direction of the truck
