Answer 2

Calculation of the Coefficient of Friction

To calculate the coefficient of friction, we need to use the formula:

Coefficient of Friction (μ) = Force of Friction (Ff) / Normal Force (Fn)

In this case, the force of friction is equal to the applied force, which is 200 N. The normal force is equal to the weight of the object, which can be calculated using the formula:

Weight (W) = Mass (m) x Acceleration due to gravity (g)

Given that the mass of the object is 50 kg and the acceleration due to gravity is approximately 9.8 m/s^2, we can calculate the weight:

Weight (W) = 50 kg x 9.8 m/s^2 = 490 N

Now, we can substitute the values into the formula for the coefficient of friction:

Coefficient of Friction (μ) = 200 N / 490 N

Calculating this, we find that the coefficient of friction is approximately 0.408.

Please note that the coefficient of friction can vary depending on the surfaces in contact and other factors. The value calculated here is an approximation based on the given information.
