Answer 1

Answer:

Escape velocity is the minimum velocity required by a body to be projected to overcome the gravitational pull of the earth. ... An object that has this velocity at the earth's surface will totally escape the earth's gravitational field ignoring the losses due to the atmosphere.

Explanation:

Given: G= 6,67 x 10-N m²/kg', mass of the moon = M = 7.34 x 1022 kg and radius of the moon = R= 1.74 x 10 m. 12 GM Escape velocit y = v esc R 2 x 6.67 x 10" X 7.34 x 1022 1.74 x 106 =2.37 km/s

 Escape velocity on the moon 2.37 km/s.

I hope this helps you
