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.

When Gabriel Fahrenheit invented the first mercury thermometer, he called "zero degrees" the lowest temperature he was able to attain with a mixture of ice and salt.
