An observer who is 3km from a launchpad watches a rocket that is rising vertically. At a certain point in time the observer measures the angle between the ground and her line of sight of the rocket to be t/3 radians. If at that moment the angle is increasing at a rate of 1/8 radians per second, how fast is the rocket rising when she made the measurement?
