A 554-kg crate is placed on an adjustable inclined plane. As one end of the incline is raised, the crate begins to move downward. If the crate slides down the incline with an acceleration of 0.76 m/s² when the incline angle is 33°, then what should the incline angle be for the crate to slide down the plane at constant speed? (g = 9.8 m/s²) Answer:
