Find the acceleration of gravity on Mars, if its mass is 6.4 * 10 ^ 23 kg, and the radius is 3397 km
| February 1, 2021 | education
m = 6.4 * 10 ^ 23 kg.
R = 3397 km = 3397 * 10 ^ 3 m.
G = 6.67 * 10 ^ -11 H * m ^ 2 / kg ^ 2.
g -?
g = G * m / R ^ 2.
g = 6.67 * 10 ^ -11 H * m ^ 2 / kg ^ 2 * 6.4 * 10 ^ 23 kg / (3397 * 10 ^ 3 m) ^ 2 = 3.69 m / s ^ 2.
Answer: g = 3.69 m / s ^ 2.
