a 331N crate resting on a plane inclined 31 degrees with the horizontal requires a 20.2N force to being in down to 7.9m from its initial position. the force is applied 65 degree with respect to the horizontal. neglecting friction between the crate and plane, determine the time (in seconds) that the crate had travelled a distance of 7.9m .
