Given:
The applied force is F = 23 N
The mass of the object is m = 7 kg
The object moves with a constant velocity of v = 6.1 m/s
The acceleration due to gravity is g = 10 m/s^2
Required: The coefficient of friction between the object and the surface.
Step-by-step explanation:
The object moves at a constant velocity, so the acceleration will be zero.
The equation of motion can be written as

So, the applied force will be equal to the frictional force.
The coefficient of friction can be calculated as

On substituting the values, the coefficient of friction will be

Thus, the coefficient of friction is 0.33
Final Answer: The coefficient of friction between the object and the surface is 0.33.
