Two objects of different masses slide up an inclined plane.

1. Homework Statement

A lightweight object and a very heavy object are sliding with equal speeds along a level frictionless
surface. They both slide up the same frictionless hill. Which rises to a greater height?
A) The heavy object, because it has greater kinetic energy.
B) The light object, because it has smaller kinetic energy.
C) The lightweight object, because it weighs less.
D) The heavy object, because it weighs more.
E) They both slide to the same height.

2. Homework Equations

W=-mg


3. The Attempt at a Solution

I was thinking that the answer is (C) , since the object is light and gravity pulls less on it than the heavy object and it can travel further distance. Any ideas?

Hi megatron99,welcome to PF.
While rising up an inclined plane, the kinetic energy is converted into potential emergy
If both the masses start rising with the same velocity, which has more KE?

The heavier object has more K.E due to more mass , so it has more P.E and i guess more height?
