For the amusement of the guests, some hotels have elevators on the outside of the building. One such hotel is 300 feet high. You are standing by a window 100 feet above the ground and 150 feet away from the hotel, and the elevator descends at a constant speed of 30 ft / sec , starting at time t = 0 , where t is time in seconds. Let θ be the angle between the line of your horizon and your line of sight to the elevator. (a) Find a formula for h(t), the elevator's height above the ground as it descends from the top of the hotel h(t) 300-25t (b) Using your answer to part (a), express θ as a function of time e. Find the rate of change of θ with respect to t. de dt to you to be moving. At what time does the elevator appear to be moving fastest? The rate of change of θ is a measure of how fast the elevator appears time tc) seconds At what height does the elevator appear to be moving fastest?
