A 483 kg car parked on a parking lot is struck from the rear by a 900-kg truck. The two vehicles become entangled, moving along the same path as that of the truck. If the entangled car and the truck move with the velocity of 10.0 m/s after the collision, what was the velocity of the truck before the collision?

Question

A 483 kg car parked on a parking lot is struck from the rear by a 900-kg truck. The two vehicles become entangled, moving along the same path as that of the truck. If the entangled car and the truck move with the velocity of 10.0 m/s after the collision, what was the velocity of the truck before the collision?

Expert Solution
Step 1

Conservation of momentum is used to calculate the truck's velocity before the collision. Conservation of momentum of the system is stated that the momentum before the collision is equal to the momentum after the collision.
