(b) (5 marks) What acceleration must the cart have so that block A does not fall? The coefficient of
static friction between the block and the cart is us.
(c) (2 marks) How would an observer on the cart describe the behavior of the block?

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…
Section II: Problems Page 3 Problem 1: Newton's Laws A1300 kg car is held in place by a light cable on a very smooth (frictionless ramp). The cable makes an angle of ß = 31° above the surface of the ramp, and the ramp itself rises & 25° above the horizontal, as shown in the figure below. (a) Draw a free body diagram of the car. Be sure to label all forces clearly and to place the angles 6 and p in your diagram. 31.0° www. 25.0° b) Find the tension in the cable FT c) How hard does the surface of the ramp push on the car?
