How Much Does Gravity Affect Weight on Mercury?

Click For Summary
SUMMARY

The acceleration due to gravity on Mercury is calculated using the formula \( g = \frac{GM}{r^2} \), where \( G \) is the gravitational constant, \( M \) is the mass of Mercury (3.30 x 10^23 kg), and \( r \) is the radius of Mercury (2.44 x 10^6 m). This results in a gravity value of approximately 3.7 m/s². Consequently, a person weighing 5.94 kg on Earth would weigh approximately 22.0 N on Mercury, demonstrating the significant impact of lower gravity on weight.

Mercury has a mass of 3.30 x10^23 kg and a radius of 2.44 x10^6 m.
(a) What is the acceleration due to gravity on Mercury?
m/s2

(b) How much would a 5.94 kg person weigh on this planet?
Ni honestly have no idea how to do this... help please!
