An experimental fireworks shell is launched vertically from point A with an initial velocity of magnitude vo = 83 ft/sec. In addition to the acceleration due to gravity, an internal thrusting mechanism causes a constant acceleration component of 1.6g in the direction shown for the first 1.9 seconds of flight, after which the thruster ceases to function. Determine the maximum height h achieved, the total flight time t, the net horizontal displacement x from point A, and plot the entire trajectory. Neglect any acceleration due to aerodynamics. Answers: h = t = 20 X = i i i 68 1.6 g ft sec ft
