    from orange heinemann book.

    I was thinking that loss in ek = wd vs friction plus the change in epe

    the change in epe in my opinion was the loss of epe upon returning to unstretched postion (was initially compressed) plus the gain in epe because it extends by a/3.

    However they just consider the gain in the answers?? Why dont they consider thte first loss? if that makes a ny sense

    thanks

    its q4 btw NOT q23
