If there is no friction, the angle of the slope doesnt matter. The mass won't matter either, after you set
M g H = (1/2) M V^2
and solve for V.
H is the vertical distance that it falls. Since you know the length L and the angle,
H = L sin 14.
A 31.0 kg crate, initially at rest, slides down a ramp 2.6 m long and inlined 14 degrees with the horizontal. Using the work-kinetic energy theorem and disregarding friction, find the velocity of the crate at the bottom of the ramp
