how is md^2r/dt^2 . dr/dt = d/dt (1/2 m (dr/dt)^2 )
Can you work it out for me explicitly ?
Can you state the chain rule? Can you apply it to the time derivative of ##(dr/dt)^2##?
2dr/dt . . is that right ?
I was able to work out the right hand side. But the left hand side is my problem. .
That makes no sense. The LHS is the answer to the derivative on the RHS. There's nothing to work out on the left.
The stackexchange link I gave you is all about why that is not the answer!
okay Got it. Thank you so much !!
