6.) A sphere of mass LaTeX Code: m hangs from a string of length LaTeX Code: l and is drawn back so that the string makes an angle of LaTeX Code: \\theta with the vertical axis. It swings down until the strings hits a peg which is LaTeX Code: l/2 directly below the point where the string is attached to the ceiling. When the string hits the peg, the sphere keeps moving and swings up through an angle LaTeX Code: \\alpha . Use conservation of energy to find an equation for the angle LaTeX Code: \\alpha . Show that this equation makes sense with a few, well-chosen examples for LaTeX Code: \\theta .

doesnt exacly show the diagram.

2. Relevant equations

to find that angle theta. I set up the two equations of 1/2mv^2 = mgh. the first one for the the relationship between the ball at the top and right before it hits the peg when its straight down.

I will scan my solution on here so the diagrams will work hopefully my attachments will be viewable.
