Static and Kinetic Friction

Kinetic friction comes into existence when there are moving surfaces means in other words we can say that the force which comes into existing between moving surfaces is known as kinetic friction.

They both slide up the same frictionless incline plane. Which box rises to a greater height? Group of answer choices A) Box A rises to the greater height because it weighs less. B)The two objects rise to the same height. C) Box B rises to the greater height because it contains more mass. D) Box A rises to the greater height because it possesses a smaller amount of kinetic energy. E) Box B rises to the greater height because it possesses a larger amount of kinetic energy.
