A box with a mass of 2,ookg rests on a horizontal surface.Calculate the maximum static friction if ms=0,4oo

F(fr) = μmg

To calculate the maximum static friction, we can use the equation:

Maximum Static Friction (Fs) = coefficient of static friction (μs) x Normal force (N)

In this case, we are given:

Mass of the box (m) = 2000 kg
Coefficient of static friction (μs) = 0.400

To find the normal force, we can use the equation:

Normal force (N) = Mass (m) x acceleration due to gravity (g)

The acceleration due to gravity is approximately 9.8 m/s². Therefore:

Normal force (N) = 2000 kg x 9.8 m/s² = 19600 N

Now we can substitute the values into the equation to find the maximum static friction:

Fs = μs x N

Fs = 0.400 x 19600 N

Fs = 7840 N

Therefore, the maximum static friction for a box with a mass of 2000 kg and a coefficient of static friction of 0.400 is 7840 N.
