I thought you had to maintain escape velocity in order to escape the Earth's pull? Hence why rockets have...well...rocketsThe 11.2 km/s does not include the effect of air resistance, that's true. Still there is a finite velocity with which a ball from the surface of the earth can be thrown to overcome both the gravitational pull of the earth and the effect of air-resistance. To launch a rocket from the surface with a starting velocity of 11.2 km/s ( a mere 40000 km/h) is not really feasible. Rockets need trust over a larger distance than an arm length to build up velocity in a way in which the forces exerted on their structure are within acceptable range.
