[QUOTE="mattwild, post: 4491816, member: 486945"] [b]AP Physics HW Help -- Motion of 2 Pendulums[/b] [h2]Homework Statement [/h2] A system consists of two metal balls hanging by strings of length L fixed at a common point as shown. Pendulum A has a mass of 2kg and Pendulum B has a period of 2.0s. a. What is the length L of each pendulum? b. What is the maximum speed Pendulum A reaches after being released from a height of 0.6m above its equilibrium position (neglect friction) c. Pendulums A and B are released at the same time from the same height, colliding right in the middle of their arcs. If Pendulum A comes to a complete stop after the collision while Pendulum B moves backward with half of its original speed, what is the mass of Pendulum B>[h2]Homework Equations[/h2] Period equations Kinetic Energy Maybe? Conservation of momentum[h2]The Attempt at a Solution[/h2] For a. I used to formula Tp=2Pi(sqrrt of L/g) For b. I have no clue maybe use something with KE and PE For c. Conservation of momentum formula I am thinking?HERE IS THE DIAGRAM: [url]http://imgur.com/GK1ZvFf[/url] [/QUOTE]
