10 The engines of a rocket sitting on the ground fire to accelerate the rocket at 3.5\,\mathrm{m/s^2}3.5m/s2 until it reaches an altitude of 1.2\,\mathrm{km}1.2km. At that point, the engines fail and the rocket is in free fall. What height does the rocket reach in \mathrm{m}m? Assume a constant...

Thank u very much I'm very grateful
