1G over 2000 km gets you to 6261 m/s, after 639 s. That isn't escape velocity. That isn't even orbital velocity.
But Fortaleza, Brazil, to Dakar, Senegal, is about 3100 km. 1G over that distance gets you to 7795 m/s, after 795 s. That can almost get you to a LEO, with a 40 degree inclination. You'd still need to overcome atmospheric drag.
Fortaleza, Brazil, to Libreville, Gabon, is 5350 km. 1G over that distance gets you to 11240 m/s, after 1045 s. That will get you into an orbit with 4 degree inclination, and after accounting for drag and the angular velocity at the equator, you might even still be at escape velocity after exiting the atmosphere.
