The crate shown in the figure (Figure 1) lies on a plane tilted at an angle θ = 30 ° to the horizontal, with μk = 0.19.
Determine the acceleration of the crate as it slides down the plane.
If the crate starts from rest at height of 8.15 m from base of the plane, what will be the crate's speed when it reaches the bottom of the incline?
