question

The initial mass of a rocket is to be 100,000 lb, of which 5 percent is to be structure, the remainder fuel and payload. If thespecific impulse of the propellant combination used is 300lb_f/lb_m/sec, calculate the payload mass that would be ableto escape from earth for a single-state and for a two- stagerocket. Neglect aerodynamic drag, gravity forces, and thetermimvolvingp_e- p_a in the thrust equation. Assume escapevelocity of 36,800 fps.
