uhhh, no you cant. Care to explain why you think you can?
Sure, this is a commonly misunderstood problem. Escape velocity is determined in part by the distance of the vehicle from the center of the earth. Start out going straight up from the earth at 50 mph and, if you have enough fuel, eventually you will be at a point far enough from the center of the earth so that escape velocity from that point is 50 mph. There are many disbelievers about this, but it's really just simple math.
