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?

10800 kg m/s

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.

(75°f − 32) × 5/9 = 23.889°c
