(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

A box weighing 80N is pulled along a horizontal surface by a force of 15 N which is directed at 20° above the horizontal. If the box started from rest and the coefficient of friction is 0.15, find the kinetic energy and velocity of the box after it traveled a distance of 10 m.

2. Relevant equations

Normal force= W-Tsinθ

Frictional force=μk x Normal force

3. The attempt at a solution

First I looked for normal force which turns out as 74.87 then frictional force which is 11.23 after that, I dont get how to find velocity. I just need final velocity at this point to get average velocity=velocity then having V, I could solve for K.E.
