    Why Is My Calculated Velocity at the Swing's Apex Incorrect?

    I see what I did wrong. I was using the PE at the top not from the pivot point. The EQ for the speed at the top of the pivot is still from TE=PE+KE TE=9.8*1.13*mass PE=9.8*.43*mass the .43 is from 1.14-.915 which gives the radius=.215 r*2=.43 This gives me 6.86 which equals KE=1/2mv^2...
