A person with a mass of 85kg. How much in newtons do they weigh on the earth and the moon?
Use W = M*g for the weight on Earth. M = 85 kg and g = 9.8 m/s^2. The answer will be in Newtons.
Divide by 6 for the weight on the moon.
833
what is the answer thought is it just 9.8n
To determine the weight of a person on Earth and the Moon, we need to use the formula:
Weight = mass × acceleration due to gravity
On Earth, the acceleration due to gravity is approximately 9.8 m/s², and on the Moon, it is about 1.6 m/s².
So, let's calculate the weight on Earth:
Weight on Earth = 85 kg × 9.8 m/s²
Weight on Earth = 833 N (approximately)
Now, let's calculate the weight on the Moon:
Weight on the Moon = 85 kg × 1.6 m/s²
Weight on the Moon = 136 N (approximately)
Therefore, a person with a mass of 85 kg weighs approximately 833 Newtons on Earth and 136 Newtons on the Moon.
