A powered model rocket is launched in the vertical direction. The altitude of the rocket is 100FT (above ground level) at the end of the powered portion of the flight. The rocket lands 19.676 seconds from the powered portion of the flight.
a) select and label a coordinate system and origin
b)Determine the speed of the rocket at the end of powered flight
c) When during the flight is this speed achieved again?
d)Determine the maximum altitude reached by the rocket
e) Check for the unpowered portion of the flight that t-up + t-down = 19.676 seconds
