2/74 An experimental fireworks shell is launched verti- cally from point A with an initial velocity of magnitude Vo = 100 ft/sec. In addition to the acceleration due to gravity, an internal thrusting mechanism causes a con- stant acceleration component of 2g in the 60 direction shown for the first 2 seconds of flight, after which the thruster ceases to function. Determine the maximum height h achieved, the total flight time, and the net hori- zontal displacement from point A. Plot the entire trajectory. Neglect any acceleration due to aerodynamics. 8 VO A 1128 60 PROBLEM 2/74
