a rectangular barge with a flat bottom, has an area at the bottom of 4m squared. the weight of the barge plus its cargo is 5,000 newtons. what is the mass of the barge + cargo in kilograms?
mass*g=weight
mass=weight/g
To determine the mass of the barge plus its cargo in kilograms, we need to use the gravitational force equation.
The formula to calculate the weight of an object is:
Weight = mass × acceleration due to gravity
The given weight of the barge plus cargo is 5,000 newtons. However, we need to convert this weight to mass in kilograms, so we rearrange the formula:
Weight = mass × acceleration due to gravity
mass = weight ÷ acceleration due to gravity
The acceleration due to gravity is approximately 9.8 m/s².
mass = 5000 N ÷ 9.8 m/s²
Now, let's calculate the mass:
mass = 510.2 kg
Therefore, the mass of the barge plus its cargo is approximately 510.2 kilograms.
