Given: Rocket mass M departs vertically from surface of earth( Re 6371km. g = 9.81m/s.Fuel is mass m. V(0) is Om/s. Exhaust velocity is r=0.05m/s. velocity (u )of expelled gas is constant and equal to u=8000m/s. Mass M = 1/4 mass m. Determine the speed v(20) and the height h(20) of the rocket after 20 secs. Did the rocket reach escape velocity v(e) fot t=20s?
