What is the mass in kg of a 3920 N piano ?
mass = weight / g
To find the mass in kilograms (kg) of a piano with a weight of 3920 Newtons (N), we can use the formula:
Weight = Mass × Acceleration due to gravity
The standard value for acceleration due to gravity on Earth is approximately 9.8 m/s^2.
Rearranging the formula, we get:
Mass = Weight / Acceleration due to gravity
Substituting the given values:
Mass = 3920 N / (9.8 m/s^2)
Mass = 400 kg
Therefore, the mass of the piano is 400 kg.
