Question

for an object on the surface of Earth calculate the escape velocity ​

Answer 1

Answer:-

Escape Velocity

Escape VelocityTo find the escape velocity, apply energy conservation: Ui + Ki = Uf + Kf

Escape VelocityTo find the escape velocity, apply energy conservation: Ui + Ki = Uf + KfFor a planet of mass M and radius R, the potential energy of an object of mass m at the planet's surface is: U= - G m M/R.

Answer 2

Answer:

Escape velocity refers to the minimum velocity which is needed to leave a planet or moon. The formula for escape velocity comprises of a constant, G, which we refer to as the universal gravitational constant. ... The value of it is = 6.673 × 10-11 N

If the kinetic energy of an object launched from the Earth were equal in magnitude to the potential energy, then in the absence of friction resistance it could escape from the Earth. vescape = mi/hr. g = gEarth.
