Wood block sliding on 25 degree angle

Click For Summary
SUMMARY

A wooden block sliding down a 25-degree inclined plane at a constant velocity of 6 m/s indicates that the forces acting on it are balanced. The coefficient of kinetic friction can be calculated using the formula for frictional force, which is equal to the gravitational component along the incline. By drawing a Free Body Force diagram and resolving the forces, the coefficient of kinetic friction is determined to be 0.4, as the frictional force equals the gravitational force component along the incline.

A wooden block slides directly down an inclined plane, at a constant velocity of 6 m/s. How large is the coefficient of kinetic friction, if the plane makes an angle of 25 degrees with the horizontal?

What have you done? show some work.
 
f=UN = 6(0.4) not sure how to begin with this problem and how to find the coefficient
 
First of all, what you should do in every problem of this type, is to choose an appropriate set of axis and draw the Free Body Force diagram.
In the inclined plane questions, it is easier to solve a problem if you choose the co-ordinate axis (ie, x&y axis) as along the plane and perpendicular to the plane.
Next, identify all the forces acting on the block and find the components of each force along the axis.
Since the body is not accelerating, what is the sum of the forces acting along the plane? Can you find the value of friction from this?
