If an object weighs 39.2 N on earth what is its mass
F = m g
39.2 = m (9.81)
m = 39.2/9.81
in kilograms
To determine the mass of an object, we can use the formula F = m * g, where F represents the weight of the object, m represents the mass, and g represents the acceleration due to gravity. On Earth, the acceleration due to gravity is approximately 9.8 m/s^2.
Given that the object weighs 39.2 N, we can set up the equation as follows:
39.2 N = m * 9.8 m/s^2
To solve for mass (m), divide both sides of the equation by 9.8 m/s^2:
m = 39.2 N / 9.8 m/s^2
m ≈ 4 kg
Therefore, the mass of the object is approximately 4 kg.
To calculate the mass of an object, we need to know the weight of the object and the acceleration due to gravity.
Weight is the force exerted on an object due to gravity and is measured in Newtons (N). On Earth, the acceleration due to gravity is approximately 9.8 m/s^2.
In this case, you mentioned that the weight of the object is 39.2 N. We can use this weight value and the acceleration due to gravity to find the mass of the object using the formula:
Weight = Mass x Acceleration due to gravity
Rearranging the formula to solve for mass, we have:
Mass = Weight / Acceleration due to gravity
Plugging in the given values, we have:
Mass = 39.2 N / 9.8 m/s^2
Calculating the result:
Mass = 4 kg
Therefore, the mass of the object is 4 kg.
