Solve the following question given below:
Question 1: A 14.0g rubber bullet hits a wall with a speed of 170m/s
Part A: If the bullet bounces straight back with a speed of 130m/s, what is the magnitude of the change in momentum of the bullet?
Question 2: A cardinal (Richmondena cardinalis) of mass 4.40×102 kg and a baseball of mass 0.144kg have the same kinetic energy.
Part A: What is the ratio of the cardinal's magnitude pc of momentum to the magnitude pb of the baseball's momentum?
I need help to determine the magnitude of the change in momentum of the bullet.
