(a) Draw a free body diagram for a stationary mass on an inclined surface. Show the forces acting, including any component forces, and indicate a coordinate system on the diagram.

(b) If the incline is at 32° to the horizontal, what is the coefficient of static friction, µs, required to keep the mass from sliding? Show full working!(4 marks) A light hangs motionless supported by two ropes. Rope 1 is at an angle of 38° to the horizontal and has a tension of 37.0 N. Rope 2 is at an angle of 68° to the horizontal. (a) Calculate the tension in Rope 2. (b) Calculate the mass of the light.
