Question

A car has 10,800 kg m/s of momentum as it collides with a trash dumpster AT REST.

How much TOTAL MOMENTUM will the car and dumpster have after collision?

Answer 1

The total momentum of the car and dumpster after the collision will be equal to the initial momentum of the car, which is 10,800 kg m/s.

Step-by-step explanation:

Momentum is defined as the product of an object's mass and its velocity. To calculate the total momentum of the car and dumpster after the collision, we need to consider the conservation of momentum. Since the dumpster is at rest initially, its momentum is zero. Therefore, the total momentum after the collision will be equal to the initial momentum of the car.

Given that the initial momentum of the car is 10,800 kg m/s, the total momentum after the collision will also be 10,800 kg m/s.

Answer 2

10800 kg m/s

Step-by-step explanation:

Since the dumpster was initially at rest, its momentum before collision equal to zero. So that the total momentum of the car and dumpster before collision is 10800 kg m/s.

The principle of conservation of linear momentum states that: in a system of colliding bodies, total momentum is conserved. Therefore, the total momentum of the car and dumpster after collision is 10800 kg m/s.
