A rock of mass m is dropped to the ground from a height h. A second rock, with mass 2m, is dropped from

the same height. When the second rock strikes the ground, its kinetic energy is (a) twice that of the first rock

(b) four times that of the first rock (c) the same as that of the first rock (d) half as much as that of the first rock

(e) impossible to determine.​

Sagot :

Answer:

A

Explanation:

The kinetic energy of an object is directly proportional to its mass. Since the second rock is twice as heavy as the first one plus they're both dropped at from the same height, then therefore, the second rock's kinetic energy is twice of that of the first one.
