What is the escape speed (in km/s) from an earth-like planet with mass 6.5e+24 kg and radius 55.0 × 105 m? use the gravitational constant g = 6.67 × 10-11 m3 kg-1 s-2.

Escape velocity, v = 12.6 km/s

Explanation:

It is given that,

Mass of earth like planet,

Radius of planet,

The escape velocity of a planet is given by the following formula as:

G = universal gravitational constant

v = 12556.05 m/s

or

v = 12.6 km/s

Hence, this is the required solution.
