An observer is 20m above the ground floor of a large hotel atrium looking at a glass-enclosed elevator shaft that is 18m horizontally from the observer. The angle of elevation of the elevator is the angle of the observer's line of sight makes with the horizontal (it may be positive or negative). Assuming that the elevator rises at a rate of 3/ms, what is the rate of change of the angle of elevation when the elevator is 11 m above the ground? When the elevator is 38m above the ground?
please show work and don't tell me to look at the other problems please there is not enough information from the others for me to figure out mine.
