V = 0.236 m/s KE = 0.014 J PEg = 2.836 J Y-pos = 0.579 m

So the initial KE that I'm working with is 0.014 J, the PEg for that value is 2.836 J, and the velocity for that value is 0.236 m/s. If I double the velocity = 2*0.236 m/s = around 0.478 m/s (I'm using 0.478 m/s because it is the next value of my data, so it would be easier to use.) With this...

A pendulum like this, but with only one swing from left to right.

This is the exact question: What % of PEg must be converted in KE in order to double the speed of the pendulum?

This is the exact question: What % of PEg must be converted in KE in order to double the speed of the pendulum?

My first value for velocity is 0.236 m/s.

Homework Statement What % of PEg must be converted in KE in order to double the speed of a pendulum? So I have spent a couple of days trying to figure out this problem (it's a lab), and I can't seem to figure it out. I have asked my physics teacher about it, and he said the answer to the...
