Multiplechoice questions may continue on the next column or page – find all choices before answering. 001 10.0 points A man makes three consecutive displace ments: (1) from O to A, (2) from A to B, and (3) back to O (refer to the figure). The mag nitude of OA is 17 . 3 m, and of AB 28 . 697 m. A B O θ If θ = 41 . 1 ◦ , find the magnitude of the third displacement. Answer in units of m. 002 10.0 points At a particular instant, a stationary observer on the ground sees a package falling with speed v 1 at an angle to the vertical. To a pilot flying horizontally at constant speed relative to the ground, the package appears to be falling vertically with a speed v 2 at that instant. What is the speed of the pilot relative to the ground? 1. radicalBig v 2 1 + v 2 2 2. radicalBig v 2 1 − v 2 2 3. v 1 − v 2 4. v 1 + v 2 5. v 2 − v 1 003 10.0 points A particle moving at a velocity of 5 . 1 m / s in the positive x direction is given an accelera tion of 7 . 5 m / s 2 in the positive y direction for 6 . 3 s. What is the final speed of the particle? Answer in units of m / s. 004 (part 1 of 3) 10.0 points Neglect: Air friction....
