A= 0m/s

B= 5m/s straight up

C= 9m/s to the right

D= 5m/s straight down

E= 8m/s at a 45 degree angle to the right

F= 8m/s to the right

Rank the balls from largest to smallest, based of their potential/kinetic/mechanical energy

Rank the balls from largest to smallest, based on their speed just before they hit the ground

Explanation / Answer

a) A>E=F>B=c>A

b)D=B>E>F=C=A
