The first part of the equation was to derive t= integral [1/sqrt((2/m)(E-U(x))] dx Part b is where I got stuck. Suppose U(x) = C/x for x>0. Calculate the time for a particle to move from x0 to 5x0 starting form rest at x0. Leave answer in terms of C,m, and x0. Evaluate the integral. I assumed the question wanted to plug in C/x in for U(x) and then sub in m(dx/dt)^2/2+C/x for E. But that doesn't work.
