Consider a wreck in which a car runs into the back of a stationary truck. Before the collision, the car has momentum forward. We will suppose that the car and truck stick together after the crash.
The law of conservation of momentum tells us what the momentum of the wreckage will be.
- What will it be equal to? (1)
- What values would we need to know to calculate the velocity of the wreckage after impact? (2)
Please drag and drop the selected option in the right place or type it instead
the momentum of the car before collision
the momentum of the car after collision
masses of car and truck, and pre-wreck velocity of the car
masses of car and truck, and pre-wreck velocity of the truck
