0 PERTA C 2000 A television camera at ground level is 2000 feet away from the launchin to take off vertically, as seen in the following figure. The angle of elevation of the camera can be found by pad of a space rocket that is set 0 = tan ¹(2000) where x is the height of the rocket. Find the rate of change of the angle of elevation after launch when the camera and the rocket are 5811 feet apart. 0' = radians per foot. (Round your answer to five docimal pl
