A 368-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 0.59 m/s2 when the incline angle is 34°, then what should the incline angle be for the crate to slide down the plane at constant speed? (g = 9.8 m/s2)

Newton's Second Law

Newton’s laws of motion describe the relationship between the motion of an object and forces acting on it. Newton’s law of motion has two types as follows:
