The crate shown in Fig. 4-60 lies on a plane tilted at an angle (theta)= 25.0 degrees to the horizontal, with (mu-of-k)= 0.19. (a) Determine the acceleration of the crate as it slides down the plane. (b) If the crate starts from rest 8.15 m up along the plane from its base, what will be the crate’s speed when it reaches the bottom of the incline?
