Pythagorean Theorem and Pendulums


1. The problem statement, all variables and given/known data
Calculate the maximum speed of the 100 g pendulum mass when it has a length of 100 cm and an amplitude of 50cm. sorry my computer won't access the other thread. i don't know any other laws of conservations of energy or trig very well. also, when the pendulum as an amplitude of 50 cm , how does this lend me knowledge.




2. Relevant equations
pythagorean theorem (i would like to use this).
a=9.8 m/s2
what does amplitude mean, the pendulums height, or how far the pendulum is from its maximum speed point


3. The attempt at a solution
max of pendulum is at bottom.
pendulum starts gainig speed of a from top till reaches bottom.
