A block weighing 5.7 N requires a force of 2 N to push it along at constant velocity.

What is the coefficient of friction for the surface?

2N=mu*mg

mu=2/5.7

.35

To find the coefficient of friction for the surface, we can use the equation:

Coefficient of friction (μ) = Force of friction (Ff) / Normal force (N)

In this case, the force required to push the block at constant velocity is equal to the force of friction. The normal force is equal to the weight of the block.

1. First, let's calculate the weight of the block:
Weight (W) = mass (m) * acceleration due to gravity (g)

We need the mass to find the weight. If the mass is not given, we can use the formula:

Mass (m) = Weight (W) / Gravity (g)

2. Determine the force of friction:
Force of Friction (Ff) = Force to push block at constant velocity

3. Calculate the coefficient of friction, using the equation:

Coefficient of friction (μ) = Force of friction (Ff) / Weight (W)

Let's calculate the values step by step:

1. Mass (m) = Weight (W) / Gravity (g)
Since the weight is given as 5.7 N, we need to find the mass. The acceleration due to gravity (g) is approximately 9.8 m/s^2. Let's calculate the mass:

m = 5.7 N / 9.8 m/s^2

2. Force of friction (Ff) = Force to push block at constant velocity
The force required to push the block at constant velocity is given as 2 N.

3. Coefficient of friction (μ) = Force of friction (Ff) / Weight (W)
We have the values for force of friction and weight, so we can substitute them into the equation:

μ = 2 N / (5.7 N / 9.8 m/s^2)

Simplifying the equation further will give us the coefficient of friction (μ).
