1.) You push a 325N trunk up a 20.0 degree inclined plane at a constant velocity by exerting a 211N force parallel to the plane’s surface. What is the sum of all forces parallel to the planes surface?
110N
211N
-211N
0 N
2.) What are the magnitude and direction of the frictional force?
0N
100N downward along the plane
111N upward along the plane
211N downward along the plane
