Question

if a man weight 900N on earth,what is his weight on jupiter where the acceleration due to gravity is 25.9 m/s

Answer 1

The mass of the man is:

$$m = \dfrac{P_e}{g_e}$$

where $P_e = 900N$ is his weight on Earth, and $g_e = 9.81m/s^2$ is the gravitational acceleration on Earth. The weight of the man on Jupiter is:

$$P_j = mg_j = \dfrac{P_eg_j}{g_e}$$

where $g_j = 25.9m/s^2$ is the gravitational acceleration on Jupiter. Thus, obtain:

$$P_j = \dfrac{900N\cdot 25.9m/s^2}{9.81m/s^2} \approx 2376N$$

Answer. 2376 N.
