A toy rocket of mass 0.25 kg is moving vertically upwards at 16 m/s when its motor stops. As the rocket continues to rise, 4.5 J of energy is dissipated to thermal stores by air resistance.
Gravitational field strength (ggg) = 10 N/kg
Calculate how much higher the rocket rises after its motor stops.
