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.
