a bowling ball has a mass of 6 kg. what happens to its momentum when it's speed increases from 2 m/s to 4 m/s

a. the initial momentum is 12 kg*m/s, and the final momentum is 24 kg*m/s.

b. the initial momentum is 12 kg*m/s, and the final momentum is 3 kg*m/s

c. the initial momentum is 6 kg*m/s, and the final momentum is 3kg*m/s

d. the initial momentum is 6 kg*n/a, and the final momentum is 12 kg*m/s

a baseball is traveling (+20 m/s) and is hit by a bat. it leaves the bat traveling (-30 m/s). what is the change in the velocity? remember that direction is what makes velocity different than speed.

a. 30 m/s
b. 50 m/s
c. 10 m/s
d. 20 m/s
