1.	A simple pedulum consisting of a mass M is attached to a string of length L. Its released from an angle alpha. A pin is located at a distance IltL, below the suspension. If theta is the maximum angle which the string makes after hitting the pin, find cos theta
Answer» `(L COS alpha+l)/(L+l)` `(LCOS alpha+l)/(L-l)` `(Lcos alpha-l)/(L-l)` `(Lcos alpha-l)/(L+l)` ANSWER :C
