Answer:
18 m
Explanation:
G = Gravitational constant
m = Mass of planet =
= Density of planet
V = Volume of planet assuming it is a sphere =
r = Radius of planet
Acceleration due to gravity on a planet is given by
So,
Density of other planet =
Radius of other planet =
Since the person is jumping up the acceleration due to gravity will be negative.
From kinematic equations we have
On the other planet
The man can jump a height of 18 m on the other planet.
