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 :Find the box's speed at t = 0.6.

to do this problem i used the conservation of mechanical energy formula and just solved for v #2 squared but apparently that wasnt right
