Question

Two identical masses are moving down a slope. One mass is traveling twice as fast as the other mass. How does the kinetic energy of one mass compare to the other?

a. The faster object has the same kinetic energy as the slower object.
b. The faster object has less kinetic energy than the slower object.
c. The faster object has twice as much kinetic energy as the slower object.
d. The faster object has four times as much kinetic energy as the slower object.

Answer 1

KE = 1/2*m*v^2
If v is 2x as much then KE is 4x as much.
