    Centripedal force velocity question.

    what is conserved?? I am guessing you mean energy. so if i use the equation final energy = initial energy with all the mass canceling out and then i find the height of tarzan in the middle of his swing in relation to tarzan at the beginning of his swing, i should be able to calculate the final...
