never come here expecting help "in a couple of minutes." you can't count on anyone's watching every post as it comes up.
The first related question below is this exact problem, just with different numbers. Always be sure to check the related questions when you do a posting. Your answer may often be already there.
An observer is 36m above the ground floor of a large hotel atrium looking at a glass-enclosed elevator shaft that is 26m 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 4/ms, what is the rate of change of the angle of elevation when the elevator is 23 m above the ground? When the elevator is 49m above the ground?
PLEASE TELL ME THE ANSWERS, I CAN'T SEEM TO UNDERSTAND HOW TO DO IT AND I HAVE A TEST IN A COUPLE OF MINUTES.
