The third stage of a rocket is injected by its booster with a velocity u of 13180 km/h at A into an unpowered coasting flight to B. At B it rocket motor is ignited when the trajectory makes an angle of 25° with the horizontal. Operation is effectively above the atmosphere, and the gravitational acceleration during this interval may be taken as 8.97 m/s2, constant in magnitude and direction. Determine the time t to go from A to B. (This quantity is needed in the design of the ignition control system.) Also determine the corresponding increase h in altitude. Answers: t= h = 158.03 122.14 43° Horiz. S km -25° -Horiz.
