A 0.75 kg rocket in a fireworks display is launched from rest and follows an erratic flight path to reach point P, as in the figure. Point P is 95 m above the starting point. In the process, 520 J of work is done on the rocket by the nonconservative force generated by the burning propellant. Ignoring air resistance and the mass loss due to the burning propellant, find the rocket's speed at Point P.
