A television camera is positioned 4 000 ft from the base of a rocket launching pad The angle of elevation of the camera has to change at the correct rate in order to keep the rocket in sight Also the mechanism f focusing the camera has to take into account the increasing distance from the camera to the rising rocket Let s assume the rocket rises vertically and its speed is 600 ft s when it has risen 3 000 ft a How fast in ft s is the distance from the television camera to the rocket changing at that moment ft s b If the television camera is always kept aimed at the rocket how fast in rad s is the camera s angle of elevation changing at that same moment rad s
