An experimental fireworks shell is launched vertically from point A with an initial velocity of magnitude v0 = 140 ft/sec. In addition to the acceleration due to gravity, an internal thrusting mechanism causes a constant acceleration component of 3.0g in the direction shown for the first 3.0 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. angle is 51 dergrees instead of 60 degrees and 3.0g instead of 2g in the picture.
In order to increase production rate, a reactor setpoint was increased from 160 psig to 190 psig. The reactor pressure transmitter was recalibrated from 0- 200 psig to 0- 300 psig. What is the percent span for the old and new setpoints?
