what is the mass of a 1000N man on earth?
You're almost there, but g=9.8 and not 10 m/s².
Weight = mg where g=9.8 m/s² on earth.
So a weight of 1000N results from a mass, m, where
m=weight/g
=1000/9.8
=102 kg.
is it 100 kg (mass)
To calculate the mass of an object, you can use Newton's second law of motion, which states that force (F) is equal to mass (m) multiplied by acceleration (a).
Given that the force (F) on the man is 1000 Newtons (N) on Earth, and the acceleration due to gravity (a) on Earth is approximately 9.8 m/s², you can use the formula:
F = ma
Substituting the known values:
1000 N = m * 9.8 m/s²
To solve for mass (m), divide both sides of the equation by 9.8 m/s²:
m = 1000 N / 9.8 m/s²
m ≈ 102.04 kg
Therefore, the mass of the 1000N man on Earth is approximately 102.04 kilograms.
To find the mass of an object on Earth, we can use the formula:
Weight = mass × acceleration due to gravity.
In this case, the weight of the man is given as 1000 Newtons (N). The acceleration due to gravity on Earth is approximately 9.8 meters per second squared (m/s²).
So, let's rearrange the formula to solve for mass:
mass = weight ÷ acceleration due to gravity.
Substituting the given values:
mass = 1000 N ÷ 9.8 m/s².
By performing the calculation:
mass ≈ 102.04 kilograms (kg).
Therefore, the mass of a 1000N man on Earth is approximately 102.04 kg.
