Ответ:
F = ma
Where: m = mass
a = acceleration due to gravity (9.8 m/s^2)
F = Force
If you are pertaining to gravitational force, the acceleration of gravity is what you will consider which is 9.8 m/s^2
Now, you are given only the volume and density. We know that Density is mass over volume:
Using this we can extract a formula for mass:
The volume of your block is 0.09 and your density is 4000
Now input that into our formula:
Now that we know that mass = 360kg, we can now solve for our force.
F = ma
F = (360kg)(9.8m/s^2)
F = 3,528 N
The answer is then D.
