In the diagram below, a box is sliding down a frictionless inclined plane. direction of motion Which free body diagram best represents this situation? 6.0 kg 60 (A) (B) (C) (D) X X X X 10. If the system below is at rest, what is the coefficient of static friction? (A) 0 (B) 0.30 (C) 0.43 (D) 0.70 7.0 kg H = ? 3.0 kg 11.
