Compute all parts of given problem:
Problem: A 15.0g rubber bullet hits a wall with a speed of 180m/s.
Part A: If the bullet bounces straight back with a speed of 110m/s, what is the magnitude of the change in momentum of the bullet?
Part B: What is the direction of the change in momentum of the bullet?
I need help to find the magnitude of the change in momentum of the bullet.
