Question

5. A ball with momentum of 16 kg x m/s strikes a ball at rest. What is the total momentum of both balls after the collision? a. -16kg x m/s b. -8 kg x m/s c. 8 kg x m/s d. 16 kg x m/s? help please ​

Answer 1

Answer:

D. 16 Kgm/s

Explanation:

Let the momentum of the two balls be A and B respectively.

Momentum A = 16 kgm/s

Momentum B = 0 kgm/s (since the ball is at rest).

Total momentum = A + B

Total momentum = 16 + 0

Total momentum = 16 Kgm/s

Momentum can be defined as the multiplication (product) of the mass possessed by an object and its velocity. Momentum is considered to be a vector quantity because it has both magnitude and direction.

Mathematically, momentum is given by the formula;

Momentum = mass * velocity
