3. You are in the middle of an empty bus which is moving straight and at the moment pictured it has started to turn as shown in the figure. When this happenedr you felt pushed outward lie. to the right]. Which of the following statements explains why? [Select all that apply; [top of A. There was a force on your torso pushing you outward [to the right]. , Yaw B. Your torso continued to move forward, but your feet moved with the lous headl which was turning left, and therefore your feet ended up to the left of your torso causing you to tilt to the right. C. There was a force of static friction pulling your feet inward (to the left]. D. You threw yourself to the ground. 5. A dollar coin (mass 8.1 g) is on a spinning turntable. The coin is 0.3 m from the center, spinning along with the turntable and moving at a constant speed of 0.4 m/s. The coefficient of static friction between the coin and the turntable is 0.6. What is the magnitude of the force of static friction acting on the coin? Express your answer in N and input the number only. Hint1: Follow the problem solving steps! The free body diagram is identical to the one in question 4. Hint2: There is nothing in the problem suggesting that the force of static friction is at its maximum value. Hint3: Don't forget to convert! 6. The "Sky Screamer" is the tallest swing ride located at Six Flags in New England. People get in seats hanging off chains that are swung around a large horizontal circle. The ride is shown schematically in the figure, but you should watch this short video to get a better sense of what this ride looks like: https://www.youtube.com/watch?v=TAuj9AySEAg. Consider a rider and a seat together as a single object. Which of the following free body diagrams correctly shows the forces acting on this combined object when it is at the rightmost point of its trajectory? (For simplicity, consider it tied to a single chain.) Hint: Follow the same approach we have always used to identify forces. DO NOT use your intuition, you will get this question wrong! A B C D E F 7. What is the direction of the acceleration acting on a rider when he/she is at the rightmost point (the speed of the rider is constant)? Hint: Where is the center of the circle around which the rider is going? A. No acceleration because speed is constant B. Forward C. Backward D. Left E. Right F. Along the string, i.e
