141 Fall 2019 #6 Please read carefully and answer properly Question Title * 1. In order to receive credit, we need your name First Name Last Name Question Title Below, a toy car travels on a track at constant speed. The lettered arrows indicate different directions, with "E" indicating a zero vector. Question Title * 2. At position 1, what is the direction of the car's velocity? A B C D E Question Title * 3. At position 1, what is the direction of the car's acceleration? A B C D E Question Title * 4. At position 2, what is the direction of the car's velocity? A B C D E Question Title * 5. At position 2, what is the direction of the car's acceleration? A B C D E Question Title * 6. At position 3, what is the direction of the car's acceleration? A B C D E Question Title I take a quick roller coaster ride through a loop-the-loop. The cart has wheels that rest on a flat track that starts us at the top of the ramp, and makes one loop to the bottom. You see below the position of the cart at the top and bottom of the loop. I am sitting on a scale during the ride. I have a mass of M. Question Title * 7. What do you know about the acceleration at the bottom? Choose the best answer. it is zero it is downwards at g it is upwards at g it is downwards at greater than g. it is upwards at greater than g. It is upwards at greater than zero. it is downwards at greater than zero. Question Title * 8. What does the scale I'm sitting on read at the bottom less than zero zero Mg between zero and Mg greater than Mg Question Title * 9. What do we know about the acceleration at the top of the loop? it is upwards at greater than g it is upwards at g or less it is downwards at g or less it is downwards at g or greater there is not enough information to tell Question Title * 10. What does the scale under me read while I am at the top of the loop? less than zero zero or greater than zero Mg greater than Mg Next
