A 5860-kg rocket is set for vertical firing. The exhaust speed is 1.17 km/s. How much gas must be ejected each second to supply the thrust needed (a) to overcome the weight of the rocket and (b) to give the rocket an initial upward acceleration of 18.3 m/s2? Note that, in contrast to the situation described in Sample Problem 7-9, gravity is present here as an external force.
