Question

Find the expression of the eascape velocity for an object on the surface of

earth, hence calculate the eascape velocity of earth.​

Answer 1

Answer:

It can achieve escape at any speed, given a suitable mode of propulsion and sufficient propellant to provide the accelerating force on the object to escape. The escape velocity from Earth's surface is about 11,186 m/s (6.951 mi/s; 40,270 km/h; 36,700 ft/s; 25,020 mph; 21,744 kn).

Answer 2

Answer:

For instance, the radius of Earth is 6,371 km . Substitute these values in the escape velocity equation v = √(2GM/R) . Calculate the result. It the case of Earth, the escape velocity is equal to 11.2 km/s .
