A box is on a rough surface that is inclined at an angle of 30.0∘ to the horizontal. A mass, m1 = 0.270 kg, is attached to a hanging mass of m2 = 105 g over an ideal pulley. a. Draw two free-body diagrams, one for each mass, showing all forces acting on them and chosen direction of motion. b. What is the value of μ that allows the block to slide down the incline at constant speed? Blank 1 c. The incline is then greased to remove the friction and the masses released again from rest. Find the tension in the string, in Newtons, Blank 2 and the acceleration of the box, in m/s2. Blank 3 d. How long, in seconds, does it take the box to slide a distance of 1.40 m along the incline? Blank 4 For this problem, SHOW ALL WORK including a free-body diagram of forces on each mass shown in the drawing below. The direction of accelerations should be clearly indicated on the sketch. Show all equations used before entering numbers. This problem should be well-structured. DO NOT ENTER UNITS WITH ANSWERS.

A small block of mass m rests on the rough, sloping side of a triangular block of block of mass M which itself rests on a horizontal frictionless table (see the figure). The rough incline surface has a coefficient of static friction μs. A) Suppose that you apply a horizontal force F to push the triangular block (see the figure). Explain what will happen to the small block if the applied force F is relatively small. You gradually increase force F, and explain what will eventually happen to the small block as the force is sufficiently large. B) Draw a free body diagram for each of the blocks m and M. What is the direction of acceleration of these two blocks when they stick and move together? How many forces act on each of the blocks m and M? How many Newton's 3rd law force pairs are there in these two free body diagrams? Set up a coordinate system fixed to the table. Is the block M an inertial frame? C) Determine the minimum horizontal force F such that the small block will start moving up the incline. Draw coordinate systems, and write down intermediate steps with equations.

A ladder (length L, and uniformly distributed mass, mL), is leaning against a wall at an angle of θ (see figure below). A man (mass mM ) is standing on a rung of the ladder that is a distance of L/3 from the floor measured along the ladder. The vertical wall is frictionless, and the horizontal floor has a non-zero coefficient of friction, μ. a) (3 Points) Draw a free body diagram indicating all forces acting on the ladder as vectors, and label each one. b) (3 Points) Determine the Normal forces (one provided by the floor, and the other provided by the wall) as functions of the available constants (θ, mM, mL, L, μ, and the acceleration due to gravity, g). c) (4 points) What value of μ is needed to keep the ladder from slipping?
