PLEASE ANSWER THIS QUESTION PLEASE ITS AN URGENT
the escape velocity of a rocket from the surface of earth is the escape velocity of the same rocket from the surface of the same rocket from the surface of a planet whose acceleration due to gravity as well as radius are 3 times that of the earth

Answer 1

Escape velocity. In physics (specifically, celestial mechanics), escape velocity is the minimum speed needed for a free object to escape from the gravitational influence of a massive body. The escape velocity from Earth is about 11.186 km/s (6.951 mi/s; 40,270 km/h; 36,700 ft/s; 25,020 mph; 21,744 kn) at the surface.
