Based on the information you know about friction discuss with your group how you could experimentally determine the coefficient

of static friction between a rough block and your incline plane. How is it similar or different to the procedure of the experiment you performed today with the smart cart? Hint: Remember the relationship between the applied force and the coefficient of static friction.

Answer:

The experiment to determine the coefficient of static friction between a rough block and an incline plane is detailed in the explanation.

Explanation:

A simple experiment is as follows:

Take a weight in which its mass is known and hold it with a roller at the end of the inclined plane with a rope.

Place the weight on the plane inclined horizontally with the ground, forming a zero degree angle.

Gradually lift the weight so that the angle of incline begins to increase.

Observe that the weight will begin to slide. This angle will be the angle theta.

In this way, the coefficient of friction will be calculated as the tangent of the angle theta.

Take a different weight and repeat the procedure to get different values of the coefficient of friction.

By averaging the coefficients of friction, a final value will be obtained.
