Use the worked example above to help you solve this problem. An Eskimo returning from a successful fishing trip pulls a sled loaded with salmon. The total mass of the sled and salmon is 50.0 kg, and the Eskimo exerts a force on the sled by pulling on the rope. Suppose the coefficient of kinetic friction between the loaded sled and snow is 0.200. (a) The Eskimo pulls the sled 4.00 m, exerting a force of 1.10 x 102 N at an angle of 0 = 0°. Find the work done on the sled by friction, and the net work. Wfric = -392 282 W. net Your response differs from the correct answer by more than 100%. J (b) Repeat the calculation if the applied force is exerted at an angle of 0 = 30.0° with the horizontal. J W fric = J W net

A warehouse worker pushes a crate along the floor, as shown in the figure (Figure 1), by a force of 19 NN that points downward at an angle of 45 degrees below the horizontal. Find the horizontal component of the push. Your answer should be positive if the force is to the right, negative if the force is to the left. Express your answer in newtons. Find the vertical component of the push. Your answer should be positive if the force is upward, negative if the force is downward. Express your answer in newtons.
A cabinet of mass 3.7 kg is at rest on a ramp as shown. What is the magnitude of the friction force on the cabinet, in Newtons? The coefficients of friction between the cabinet and ramp are Ps = 0.850 and uk = 0.750. Use g = 10 m/s2. (Hint: what type of friction is it?) Your answer needs to have 2 significant figures, including the negative sign in your answer if needed. Do not include the positive sign if the answer is positive. No unit is needed in your answer, it is already given in the question statement. 30.0
Consider the system in the picture below: a cart of mass M with a static friction coefficient u is connected through a massless string to a hanging mass m. M is a capital letter, m is lower case. Write them as such, or vour equations will be confusing, M We want to find the maximum value of the hanging mass m such that the system is in equilibrium. 1. Free body diagram (FBD): Draw a FBD for each: the Cart and the hanging mass. Clearly show all the forces. 2. Clearly write the equilibrium equations for the cart in the horizontal and vertical direction. 3. Clearly write the equilibrium equation for the hanging mass. 4. Solve the system of the three equations above for the hanging mass m. Show your calculation to get credit. 5. What would happen if mass m exceeds this value? Explain.
