Physics

This force can either push the block upward at a constantvelocity or allow it to slide downward at a constant velocity. Themagnitude of the force is different in the two cases, while thedirectional angle θ is the same. Kinetic friction exists betweenthe block and the wall, and the coefficient of kinetic friction is0.310. The weight of the block is 55.0 N, and the directional anglefor the force Upper F Overscript right-arrow EndScripts is θ =31.0°. Determine the magnitude of Upper F Overscript right-arrowEndScripts when the block slides (a) up the wall and (b) down thewall.
