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).
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.
