A toy rocket, weighing 10 N, blasts straight up from ground level with a kinetic energy of 40 J. At the exact top of its trajectory, its total mechanical energy is 140 J. (By this point the rocket fuel has been completely exhausted.) To what vertical height does it rise? (Assume the referent level for the potential energy is the ground.) a) 1.0 m b) 10 m c) 24 m d) 14 m
