Answer 2

Calculating the Mass of the Concrete Slab

To calculate the mass of the concrete slab, we can use the formula for gravitational force:

Gravitational force (F) = mass (m) × acceleration due to gravity (g)

Given that the gravitational force acting on the submerged concrete slab is 2400 N, and the acceleration due to gravity is approximately 9.81 m/s², we can rearrange the formula to solve for the mass (m):

mass (m) = Gravitational force (F) / acceleration due to gravity (g)

Calculation

Using the given gravitational force of 2400 N and the acceleration due to gravity of 9.81 m/s²:

mass (m) = 2400 N / 9.81 m/s²

mass (m) ≈ 244.9 kg

Therefore, the mass of the concrete slab is approximately 244.9 kilograms.
