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 block of mass 3.3 kg is attached to a string that passes over a pulley. The block is initially held at rest, and then pulled by a force F = 84 N to the right, as shown in the figure. The pulley is like a disk of mass 0.6 kg and radius 0.8 cm, and is frictionless. What will be the kinetic energy of the block when it has moved up a distance 2.2 m?

A block of mass m = 5.78 kg is attached to a spring that is resting on a horizontal, frictionless table. The block is pushed into the spring, compressing it by 5.00 m, and is then released from rest. The spring begins to push the block back toward the equilibrium position at x = 0 m. The graph shows the component of the force (in newtons) exerted by the spring on the block versus the position of the block (in meters) relative to equilibrium. Use the graph to answer the questions. How much work W is done by the spring in pushing the block from its initial position at x = −5.00 m to x = 2.86 m? W = J What is the speed v of the block when it reaches x = 2.86 m? v = m/s What is the maximum speed vmax of the block? vmax = m/s
