How much would 80.0 kg person weight (a) on Mars, where the acceleration of gravity is 3.93 m/s2, and (b) on Earth's Moon, where the acceleration of gravity is 4.63 m/s2?
To calculate the weight of a person on Mars and the Moon, you can use the formula:
Weight = mass × acceleration due to gravity
(a) Weight on Mars:
Given: Mass = 80.0 kg, Acceleration due to gravity on Mars (g) = 3.93 m/s^2
To find the weight on Mars, we can substitute the given values into the formula:
Weight = 80.0 kg × 3.93 m/s^2
Calculating the weight on Mars:
Weight = 314.4 N
Therefore, an 80.0 kg person would weigh 314.4 N on Mars.
(b) Weight on the Moon:
Given: Mass = 80.0 kg, Acceleration due to gravity on the Moon (g) = 4.63 m/s^2
To find the weight on the Moon, we can substitute the given values into the formula:
Weight = 80.0 kg × 4.63 m/s^2
Calculating the weight on the Moon:
Weight = 370.4 N
Therefore, an 80.0 kg person would weigh 370.4 N on the Moon.
