mass=1.0

static friction=3.92

what is the coefficient static friction?

1 answer

The coefficient of static friction can be calculated using the formula:

Coefficient of static friction = Static friction force / Normal force

In this case, the static friction force is 3.92 and the normal force is equal to the weight of the mass, which is mass x gravity. Assuming gravity is 9.8 m/s^2, the normal force would be:

Normal force = mass x gravity
Normal force = 1.0 kg x 9.8 m/s^2
Normal force = 9.8 N

Therefore, the coefficient of static friction would be:

Coefficient of static friction = 3.92 N / 9.8 N
Coefficient of static friction ≈ 0.4

So, the coefficient of static friction is approximately 0.4.
