If your robot were traveling 35 MPH, it'd be able to cross a football field in six seconds. Can it?

if you have efficient gearboxes the motor should be able to get fairly close to its rated freespeed.
it'll just take a while to get there, but the only resistive forces it would need to overcome would be innefficiency in the gearbox and wind resistance.
