21. First Jane, then Ana, then Neche, now it's Elizabeth's turn. (How do people keep winding up on boats in the middle of the sea?) Elizabeth is in a rowboat in Lake Michigan, and is going to use her navigational orienteering and calculus expertise to minimize the amount of time it will take her to get to her destination on shore. Elizabeth's rowboat can only travel at 3.6 mph, but she can run at 8.8 mph because she's quick in the open field (hehehe, field joke). If Elizabeth's boat is currently 6.2 miles due east from the closest point on shore in Milwaukee, and she is headed to the Journal-Sentinel offices (to protest the difficulties of AP Biology) that is located 7.1 miles due south of that point on shore, how far north of the Journal-Sentinel offices should Elizabeth land in order to arrive there the fastest? A) 8.823 miles B) 1.108 miles C) 2.780 miles D) 6.837 miles E) 7.726 miles F) 5.992 miles G) 4.320 miles H) 1.941 miles D) 5.819 miles None of the above22. The position equation for the movement of a particle is given by 50') = \\H'3 +1 where s is measured in feet and t is measured in seconds. Find the acceleration of the particle at 2 seconds. A) 3 feetr'secz 2 B} 3 foot/sec2 C) % format/sec2 - l D) 3 foot/sec2 E) None of these
