Two cannonballs are dropped from a second floor physics lab at height h above the ground. Ball B has four times the mass of ball A. When the balls pass the bottom of a first floor window at height above the ground, the relation between their kinetic energies, KA and KB, is

◦
KA = 4KB.

◦
KA = 2KB.

◦
KA = KB.

◦
KB = 2KA.

◦
KB = 4KA.
