A rocket is being launched into space, on a vertical trajectory. 2 km away from the launch pad, a camera films this event from the ground. The camera is pointed

directly at the rocket during the entire launch. When the rocket is 2 km off the ground, it is traveling at a speed of 0.2 m. (a) [2 points] Draw a sketch depicting this scenario. Label all variables used in part (b) below. (b) [6 points] At the instant when the rocket is 2 km off the ground, how quickly is the angle of elevation of the camera increasing? (i.e. the acute angle swept out from the horizontal up to the rocket.)
