You are dragging your 25-kg backpack with a 200-N force along the ground at an angle of 50° above horizontal. The frictional force is 100 N. (a) What is the normal force? (b) What is the coefficient of friction between your backpack and the floor? (c) What is the acceleration of your backpack?

An ascending elevator, hanging from a cable, is coming to a stop. part a part complete identify all forces acting on the elevator from the list below. select all that apply. select all that apply. kinetic friction normal force tension weight static friction submitprevious answers correct part b draw a free-body diagram of the object. draw the vectors starting at the black dot. the location and orientation of the vectors will be graded. the exact length of your vectors will not be graded but the relative length of one to the other will be graded.
