Question 1.) A block with mass of 10.00 kg is on a slope of angle θ 30.0° to the horizonal (see figue below). The static friction coefficient between the block and the surface is 0.600 m. What is the static friction force? (use figure 1) ANSWER OPTIONS: a.) 40. N  b.) 50.9 N c.) 84.8 N d.) the body slides down the slope

Two blocks are connected by a (massless) string that passes over a (massless, frictionless) pulley as shown: What is the tension in the string? Express your answer in N.

A 5 kg box is at placed on a rough horizontal surface.  The coefficient of kinetic friction between the surface and the box is 0.2.  Now 20 N force is applied on the box 300 above horizontal.    Label all forces acting on the box. Determine the acceleration of the box. If applied force is removed after 10 seconds, calculate total distance the box moves along the surface.

3. Consider an inclined plane with two balls suspended as shown below. The pulley has negligible mass and both the pulley and the surface of the incline are frictionless.a. If one of your classmates calculated that, once released, the acceleration of the blocks would be 43?, without doing any calculations, say whether or not this could be a reasonable value for the acceleration.b. Draw and label a free body diagram (FBD) for each ball. (Don’t break any forces into components for the FBDs—save that work for the next question. Be sure your drawings show clearly any information you know about the directions and relative magnitudes of the forces.) Rank the relative magnitudes of all forces in your FBDs. (I’m looking for a single ranking that includes every different force in both FBDs, separated by <, >, or =.)Ball A: Ball B:relative sizes of the magnitudes of all forces in FBDs:__________________________________________________________________c. Use the FBDs from the previous…

3. A box of 20 kg is resting on a slope as shown in the diagram. 30° a) Label all the forces acting on the box. b) Calculate the normal reaction force the slope exerts on the box.
