AI Thread Summary
To find the acceleration of a snowboarder on a 5.5° slope with a coefficient of friction of μk=0.10, it is essential to start with a free body diagram illustrating all forces acting on the snowboarder. The next step involves defining a coordinate system to clarify the direction of motion. Calculating the net force using these forces will lead to determining the snowboarder's acceleration in m/s². The discussion emphasizes the importance of correctly setting up the free body diagram for accurate calculations. Properly following these steps will facilitate solving the problem effectively.

Consider a snow boarder going up a 5.5° slope. Assume the coefficient of friction for waxed wood on wet snow is μk=0.10 and he is moving in the positive direction.
Calculate the magnitude of the acceleration of the snow boarder in m/s2.

All right. So the procedure is to first draw a diagram showing all the forces on the body, then specifying a coordinate system, which specifies what you mean by "moving in the positive direction." The diagram is called a free body diagram. Once you draw the diagram, we can take the next steps easily.

This is the FBD, but I do not think it's correct.

I have recently been really interested in the derivation of Hamiltons Principle. On my research I found that with the term ##m \cdot \frac{d}{dt} (\frac{dr}{dt} \cdot \delta r) = 0## (1) one may derivate ##\delta \int (T - V) dt = 0## (2). The derivation itself I understood quiet good, but what I don't understand is where the equation (1) came from, because in my research it was just given and not derived from anywhere. Does anybody know where (1) comes from or why from it the...
