With what force does the wind press on the sail of the yacht if the sail area is 60 m2 and the wind pressure is 80 Pa?

We write down the formula for determining the force in letter form.

F = P * S,
Where:

F is the force that acts on the surface of the sail;

P is the wind pressure that acts on the sail surface;

S is the sail area of the yacht.

We substitute the known values from the condition of the problem into the formula and we get:

F = 80 * 60 = 4800 N.

4800 N = 4800/1000 = 4.8 kN.

Answer: A force of 4800 Newtons acts on the surface of the sail.
