Answer:

d. Its magnitude and its direction both remained the same.

Explanation:

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;

[tex] Momentum = mass * velocity [/tex]

The law of conservation of momentum states that the total linear momentum of any closed system would always remain constant with respect to time.

This ultimately implies that, the law of conservation of momentum states that if objects exert forces only on each other, their total momentum is conserved.

In this scenario, a rubber ball moving at a speed of 5 m/s hit a flat wall and returned to the thrower at 5 m/s. Thus, the statement which correctly describes the momentum of the rubber ball is that its magnitude and its direction both remained the same because its velocity didn't change while returning to the thrower.

The correct statement should be "Its magnitude remained the same but its direction changed". Option C is correct.

Given information:

A rubber ball moving at a speed of 5 m/s hit a flat wall and returned to the thrower at 5 m/s.

Now, the mass of the ball doesn't change and the magnitude of the velocity is also the same.

Momentum can be defined as the product of mass and velocity. It is a vector quantity because velocity is also a vector quantity, and it has magnitude and direction.

Now, the magnitude of momentum will be the same because mass and velocity don't change in magnitude.

The direction of velocity will be reversed. So, the direction of momentum will also be reversed.

Therefore, the correct statement should be "Its magnitude remained the same but its direction changed". Option C is correct.
