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.

In the figure shown below, one end of a cord is attached to the floor and the other end is attached to a small set of essentially massless wheels through a slot in a track on which the wheels roll without friction. As a result of this arrangement, the upper end of the cord is essentially free. At equilibrium, the cord is vertical and motionless. When it carries a small amplitude wave, the cord is under a uniform tension of 1.20 N. The cord has a mass of 5.80 g and a length of 85.0 cm. (a) Find the speed (in m/s) of the transverse waves in the cord. m/s (b) The cord's vibration possibilities are a set of standing-wave states, each with a node at the fixed bottom end and an antinode at the free top end. Find the node-antinode distances (in m) for the first three harmonics. Enter your answers from the lowest to the highest harmonic. m m m (c) Find the frequency (in Hz) of each of these states. (Enter your answers from simplest to more complicated.) Hz Hz Hz (d) What If? The wheels get stuck on the track and are unable to move, hence making the cart stationary. Determine the node-antinode distance (in m) and frequency of vibration (in Hz) for the third harmonic. distance m frequency Hz
