What is the escape speed from a planet with mass M-4.28x10 kg and radius R-5.45x10 m2

Question

Question

Answer 1

Answer #1

Escape speed Vesc^2 = 2 GM/R

G is universal gravitational constant

M is mass of the planet

R is Radius

VEsc^2 = 2 * 6.67 *10^-11 * 4.28 *10^25/(5.45 *10^6)

Vesc = 32.3 km/s
