A group of students launches a model rocket in the vertical direction. Based on tracking data, they determine that the altitude of the rocket was 27.5 m at the end of the powered portion of the flight 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 g-9.81m/s, determine (a) the speed v of the rocket at the end of powered flight, (b) the maximum altitude reached by the rocket. locks of mass 50 kg and 40 kg are connected by a light inextensible string as shown in
