Agroup of students launches a model rocket in the vertical direction. based on tracking data, they determine that the altidude of a rocket was 89.6 ft at the end of the powered portion of the light and that the rocket landed 16 s later. knowing that the descent parachute failed to deploy so that the rocket fell freely to the ground after reaching its maximum altitude and assuming that = 32.2 / 2 , determine (a) the speed of the rocket at the end of powered flight, (b) the maximum altitude reached by the rocket.
