# Work and Energy Problem

## Homework Statement

A sled is being pulled across a horizontal patch of snow. Friction is neglibile. The pulling force points in the same direction as the sled's displacement, which is along the +x axis. As a result, the kinetic energy of the sled increases by 38 percent. By what percent would the sled's kinetic energy have increased if the force had pointed 62 degrees above the +x azis?

## Homework Equations

I'm not sure, all i have for KE is ...

KE= 1/2 mv2

Welcome to Physics Forums.

Do you have any intuition about this? Will pulling upward give a greater or lesser speed, or will it be the same?
