10. An airplane flying 390 feet per second at an altitude of 5000 feet flew directly over an observer. The image shows the relationship of the airplane to the observer at a later time. a.) Find an equation relating x and y. 5000°t 390 5000 b.) Find the value of x when y is 6,250. Observer c.) How fast is the distance from the observer to the airplane changing at the time when the airplane is dy at the time when dt dx = 390 and y = 6,250? dt 6,250 feet from the observer? That is, what is

6. Find the angle above the horizon of the airplane as seen by the observer. Problem 5. Two traffic cops are sitting stationary at positions ri = At t = 0, a car is at the origin with instantaneous velocity v. At that time, officers 1 and 2 measure line-of-sight speeds vi and v2 on their radar guns. Determine the car's velocity v at t = 0. î+j and r2 = -j, respectively.
