1. The problem statement, all variables and given/known data A particle of mass m moves in one dimension subject to the potential energy given by: U(x) = -Uoe-(x/l)2 where Uo is a positive constant with units of energy. Supposing that at time t=0 the mass has zero velocity and is located at position 0.01l, what is the position of the mass for all subsequent times? 2. Relevant equations ? 3. The attempt at a solution ?
