thank you again are you hinting at the negative sign on the mg term?

thank you so taking v[0] as zero at the top of the first hill by cons energy i have mgH[a] = 1/2 mv[2] at the bottom of the hill... N-mg = mv2 / r yields either v2 =gr or v2 = 3gr based on parameters of question. using this in the conservation of energy will yield: h[a] = 1/2 (r) if N=0...
