When Does a Pendulum Reach Its Maximum Speed?

AI Thread Summary
The maximum speed of a simple pendulum occurs at the lowest point of its swing. To determine the time it takes to reach this speed, the period of the pendulum can be calculated using the formula T = 2π√(L/g), where L is the length of the string and g is the acceleration due to gravity. Mechanical energy is conserved throughout the pendulum's motion, meaning potential energy at the highest point converts to kinetic energy at the lowest point. For a 0.60 m long pendulum, the period can be calculated to find the time to reach maximum speed. Understanding these principles clarifies the pendulum's motion and speed dynamics.

A simple pendulum is made from a 0.60 m long string and a small ball attached to its free end. The ball is pulled to one side through a small angle and then released from rest. After the ball is released, how much time elapses before it attains its greatest speed?

So would the max speed be at the bottom of the drop? Do i need to use an energy equation of some sort?? All i know is the length of the string is .60m. I'm lost.

Hint 1: What's the period of a simple pendulum?
Hint 2: Is mechanical energy conserved?
 
Kindly see the attached pdf. My attempt to solve it, is in it. I'm wondering if my solution is right. My idea is this: At any point of time, the ball may be assumed to be at an incline which is at an angle of θ(kindly see both the pics in the pdf file). The value of θ will continuously change and so will the value of friction. I'm not able to figure out, why my solution is wrong, if it is wrong .

TL;DR Summary: I would like to know the voltmeter readings on the two resistors separately in the picture in the following cases , When one of the keys is closed When both of them are opened (Knowing that the battery has negligible internal resistance) My thoughts for the first case , one of them must be 12 volt while the other is 0 The second case we'll I think both voltmeter readings should be 12 volt since they are both parallel to the battery and they involve the key within what the...
