On aircraft carriers, catapults are used to accelerate jet aircraft to flight speeds in a short distance. One such catapult takes a 18,100-kg jet from 0 to 65 m/s in 2.7 s. (Assume the catapult acts in the positive horizontal direction. Indicate the direction with the sign of your answer where appropriate.) (a) What is the acceleration of the jet in m/s2?   m/s2 What is the acceleration of the jet in g's?   g (b) How far does the jet travel while it is accelerating?   m (c) How large is the force that the catapult must exert on the jet?   N
