A skier slides down a slope 10.2m long, inclined at an angle (theta) to the horizontal. The coefficient of kinetic friction is 0.11. Skier's initial speed is 1.9m/s and final speed at the bottom of the slope is 8.3m/s. Find (theta), air resistance is negligible.(adsbygoogle = window.adsbygoogle || []).push({});

I have applied F=ma and Work(friction) = (delta)Kinetic Energy + (delta) Potential Energy to it and found that these two r mathematically equivallent and terms just cancel when i substitue, can any1 help me with this one?

Thx
