The world’s fastest warship belongs to the united states navy. this vessel, which floats on a cushion of air, suppose that during a training exercise the ship accelerates +2.67 m/s2, so that after 15.0 s its displacement is +6.00 × 102 m.
assume that the ship moves in a straight line.
calculate the ships final velocity after the acceleration.
