IF A PERSON'S WEIGHT IS 850 N WHAT IS THE PERSON'S MASS IN KG?
Weight = Mass x (acceleration of gravity)
Usually written as:
W = M g
Therefore M = W/g
g = 9.8 m/s^2
W must be in Newtons when you use the equation; you already have that number. (850 N).
To calculate the person's mass in kilograms, we need to use the formula:
Weight = mass * gravitational acceleration (W = mg)
Given that the weight of the person is 850 N, and the gravitational acceleration on Earth is approximately 9.8 m/s^2, we can rearrange the formula to solve for mass:
mass = weight / gravitational acceleration
Substituting the values, we have:
mass = 850 N / 9.8 m/s^2
mass ≈ 86.7 kg
Therefore, the person's mass is approximately 86.7 kilograms.
To calculate a person's mass in kilograms, you need to use Newton's second law, which states that force equals mass times acceleration (F = ma). In this case, the force is the weight of the person, which is given as 850 Newtons.
To determine the person's mass, rearrange the formula to solve for mass (m):
m = F/a
Since weight is the force acting on the person due to gravity, we can use the acceleration due to gravity as the acceleration value. On Earth, the acceleration due to gravity is approximately 9.8 m/s^2.
Plugging in the values:
m = 850 N / 9.8 m/s^2
After performing the calculation, the person's mass is approximately 86.7 kilograms (kg).
