15. Your car is traveling behind a jeep. Both are moving at the same speed, so the velocity of the jeep relative to you is zero. A spare tire is strapped to the back of the jeep. Suddenly the strap brcaks, and the tire falls off the jeep. Will your car hit the spare tire before the tire hits the road? Assume that air resistance is absent. (a) Yes. As long as the car doesn't slow down, it will hit the tire. (b) No. The car will not hit the tire before the tire hits the ground, no matter how close you are to the jeep. (c) If the tire falls from a great enough height, the car will hit the tire. (d) If the car is far enough behind the jeep, the car will not hit the tire. 16. The drawing shows two cars traveling in different directions with different speeds. Their velocities are: VAG = velocity of car A relative to the Ground = 27.0 m/s, due east VuG = velocity of car B relative to the Ground = 21.0 m/s, due north The passenger of car B looks out the window and sees car A. What is the velocity (magnitude and direction) of car A as observed by the passenger of car B? In other words, what is the velocity Van of car A relative to car B? Give the directional angle of Van with respect to due east.
