A jet plane on the deck of an aircraft carrier is accelerated before take-off using a catapult. The mass of the plane is 3.2 × 104 kg and it is accelerated from rest to a velocity of 55 m s–1 in a time of 2.2 s. Calculate the mean acceleration of the plane and the distance over which the acceleration takes place.
