AP Physics HW Help -- Motion of 2 Pendulums
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>
Period equations
Kinetic Energy Maybe?
Conservation of momentum
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:
