121 Spring 2018 #5 Please read carefully and answer properly Question Title * 1. Your Name: Question Title The next three questions refer to a toy car which can move to the right or left along a horizontal line (the positive part of the distance axis). Assume that friction is so small that it can be ignored. A force is applied to the car. Choose the one force graph (A through H) for each statement below which could allow the described motion of the car to continue. You may use a choice more than once or not at all. If you think that none is correct, answer choice J. Question Title * 2. The car moves toward the right and is speeding up at a steady rate (constant acceleration). A B C D E F G H J Question Title * 3. The car moves toward the left (toward the origin) with a steady (constant) velocity. A B C D E F G H J Question Title * 4. The car moves toward the right, speeds up and then slows down. A B C D E F G H J Question Title USE THE STATEMENT AND FIGURE BELOW TO ANSWER THE NEXT TWO QUESTIONS. The accompanying figure shows a frictionless channel in the shape of a segment of a circle with center at "O". The channel has been anchored to a frictionless horizontal table top. You are looking down at the table. Forces exerted by the air are negligible. A ball is shot at high speed into the channel at "p" and exits at "r." Question Title Question Title * 5. Which path in the figure above would the ball most closely follow after it exits the channel at "r" and moves across the frictionless table top? A B C D E Question Title * 6. Consider the following distinct forces: 1. A downward force of gravity. 2. A force exerted by the channel pointing from q to O. 3. A force in the direction of motion. 4. A force pointing from O to q. Which of the above forces is (are) acting on the ball when it is within the frictionless channel at position "q"? 1 only. 1 and 2. 1 and 3. 1, 2, and 3. 1, 3, and 4. Done
