A 7710-kg rocket is set for vertical firing from the earth's surface. If the exhaust speed is 1350 m/s, how much gas must be ejected each second in order for the thrust to be equal to the weight of the rocket?
How much gas must be ejected each second to give the rocket an initial upward acceleration of 17 m/s2?
