A 6 kg box slides down a long, frictionless(adsbygoogle = window.adsbygoogle || []).push({});

incline of angle 34 degrees. It starts from rest at time

t = 0 at the top of the incline at a height 17 m

above the ground.

The acceleration of gravity is 9.81 m/s^2 :

What is the original potential energy of

the box relative to the ground?

i just dont know what to do with the angle. the formula is U = mgy, but where does the angle come into play?
