Calculate the magnitude of the change in momentum in each of the following examples.
A 1,200 kg car accelerates from rest to a speed of 20 m/s.
A 75 g pellet moving at 18.0 m/s hits a tree and lodges in it.
A 250 g rubber ball hits the floor at 10.0 m/s and rebounds at 6.0 m/s.
A 60 kg student jogging at 3.0 m/s speeds up to 6.5 m/s.
