Q16 A helicopter is rising straight up in the air. The distance from the ground t seconds after takeoff is s(t) feet, where s(t) = t² + t. (a) How high did the helicopter rise in the first 5 seconds? (b) How fast is the helicopter rising if it is 20 feet off the ground? (c) How far off the ground is the helicopter if it is rising at a rate of 13 ft/sec?
