Question

Two children, totaling 200 kg, are traveling at 10 m/sec in a 100-kg bumper car during an
amusement park ride. They deliberately collide with an empty second car, mass 100 kg, which is
at rest. What is the momentum of the empty car?

Answer 1

Answer:

0kgm/s

Explanation:

The momentum of the empty car is zero.

Momentum is the quantity of motion a body possess. The more the mass and velocity by which a body moves, the higher is its momentum.

 Momentum  = mass x velocity

Since the second car is at rest, the velocity is 0m/s;

 So;

     Momentum  = 100 x 0 = 0kgm/s

Therefore, a body at rest has zero momentum
