Answer:
THE RUBBER BALL
Step-by-step explanation:
From the question we are told that
The mass of the rubber ball is

The initial speed of the rubber ball is

The final speed at which it bounces bank

The mass of the clay ball is

The initial speed of the clay ball is

The final speed of the clay ball is

Generally Impulse is mathematically represented as
where
is the change in the linear momentum so

For the rubber is


=>

For the clay ball


=>

So from the above calculation the ball with the a higher magnitude of impulse is the rubber ball
