A rubber ball thrown at a speed of 5 m/s hit a flat wall and returned to the thrower at a speed of 5 m/s. Which
statement correctly describes the momentum of the rubber
ball?

See the explanion below

Explanation:

Linear momentum is defined as the product of mass by velocity and can be calculated by the following equation.

where:

P = momentum [kg*m/s]

m = mass [kg]

v = velocity [m/s]

When the ball hits the wall it receives a force for a very short time, this time and force value is known as momentum and can be calculated by the following expression.

where:

m₁ = mass of the ball [kg]

v₁ = 5 [m/s]

v₂ = 5 [m/s]

v₁ = v₂

It can be said that the impulse is equal to 2 times the speed of throwing by the mass.
