A4350 kg truck, driving 7.39 m/s, runs into the back of a stationary car. after the collision, the truck moves 4.55 m/s and the car moves 11.5 m/s, both in the same direction. what is the mass of the car?

The mass of the car is 1074.26 kg.

Explanation:

Let the mass of the car be x.

Given:

Mass of truck, kg

Initial velocity of truck, m/s

Initial velocity of car, m/s

Final velocity of truck, m/s

Final velocity of car, m/s

When two bodies collide with no external force acting on the system, their total momentum remains conserved.

Therefore, initial momentum = final momentum

Hence, the mass of the car is 1074.26 kg.
