Question 1: Draw a free-body diagram of the block and cart (treated as a single mass) as soon as they leave the spring at the top of the ramp. If you were to double the mass of the block and cart (treated as a single mass), what effect would this have on their displacement down the slope? Question 2: Draw a free-body diagram of the block and red cart (treated as a single mass) when they are being pushed at a constant velocity.

1. A block of mass m is placed on the right side of a cart; the cart and the block are accelerating to the right with acceleration a, and the coefficient of static friction between the cart and the block is Ī¼s. The system is sketched below. a) [10 points] Explain qualitatively why the block won't slip and fall if the acceleration of the cart is large enough. b) [15 points] Draw a free body diagram for the block and label all the forces acting on it. Calculate the minimum acceleration necessary to keep the block from falling. c) [15 points] Suppose that the system block plus cart is moving with constant speed v along the inclined plane of angle Īø as shown in the figure below. What is the minimum angle Īø for which the block will stay at rest with respect to the cart?

1. Draw a free body diagram for a cart on a frictionless track being pulled to the right by a string with tension T; call this mass m1. This mass is accelerating to the right. 2. Draw a free body diagram for a mass hanging on a string with tension T2 that is accelerating downward; call this mass m2. 3. If the two masses above are connected by the same string, how are the accelerations of the two masses related? 4. If the two masses above are connected by the same string, how are the tensions of the two masses related? 5. Apply Newton's 2nd law to each mass in turn. From these two equations, solve for the acceleration of the system in terms of m1, m2 and g only. 6. Sketch a free body diagram for the cart for the cart system in section Friction below. What do you expect the graph of velocity vs. time to look like?

Draw a free body diagram for the cart moving toward the pulley at a constant velocity (moving in the +x direction). Label the mass of the cart as mc. Indicate the direction of all velocities and accelerations on your free body diagram. Calculate the magnitude of the frictional force on the cart in terms of mc and a. Show your work. mc = 0.297 kg and a = 0.233 m/s^2 and the hanging mass is 0.005 kg. Now calculate the amount of mass that must be added to the hanger (0.005 kg) so that the cart will have zero acceleration when moving toward the pulley.
