find the KE at the lowest point: 1/2 m v^2
Now, take that value,and set it equal to mgh
find h.
That is the height the bob goes up.
Now, angle= arccos(l-h)/l
make your drawing, and confirm that.
Yes I see what you're saying after drawing the diagram...So for the first bit we just use plain substitution of GPE formulas and second bit is trig.
=) thanks that seemed easier than i thought.
