A model rocket is moving vertically upwards at 18 m/s when its motor stops. For the next 2.4 s, gravity is the only force acting on the rocket.
Use g=10 m/s2g=10\ \mathrm{m/s^2}g=10 m/s2 and take upwards as positive.
Calculate the velocity of the rocket after the 2.4 s interval.
Give its magnitude and direction.
