Can you please show your intermediate steps? Thanks!

5. A gym teacher, Mr. Chambers, throws (v 25 m/s) a basketball (m 0.60 kg) at a friend standing in front on you because your friend was talking when he should be silent. (Your friend ducks because he was paying enough attention, but you get hit because although you were silent, you were not paying attention.) (This next part is made up.) Mr. Ch ambers then offers your friend a choice. Mr. C will throw a medicine ball (m -7 kg) at the friend, and the friend must catch it or be pummeled (beaten) by the entire class. Your friend must choose to have the medicine ball thrown with the same kinetic energy as the basketball, the same momentum as the basketball, or the same velocity as the basketball. If your friend wants to avoid further abuse, which should he choose? Explain.
