Question

A ball traveling with an initial momentum of 5.1 kgm/s bounces off a wall and comes back in the opposite direction with a momentum of -4.3kgm/s.

What is the change of momentum of the ball?
What impulse is required to produce this change?

Answer 1

Answer: Change in momentum=9.4kgm/s

Impulse=9.4kgm/s

Step-by-step explanation:

Change in momentum=5.1-(-4.3)=5.1+4.3=9.4kgm/s

Impulse=Change in momentum

There impulse=9.4kgm/s
