5. A0.20-kg rocket in a fireworks display is launched from rest and follows an erratic flight path to reach the point P, as Figure shows. Point P is 29 m above the starting point. In the process, 425 J of work is done on the rocket by the nonconservative force generated by the burning propellant. Ignoring air resistance and the mass lost due to the burning propellant, find the speed vr of the rocket at the point P.
