A 12000 kg airplane launched by a catapult from an aircraft carrier is accelerated from 0 to 200 km/h in 3 s. (a) How many times the acceleration due to gravity is the airplane's acceleration? (b) What is the average force the catapult exerts on the airplane?

    v=200 km/h =200000/3600=55.56 m/s,

    a=(v-v₀)/t=(55.56-0 )/3=18.52 m/s²,

    a/g= 18.52/9.8= 1.89,

    F=ma=12000•18.52=2.22•10⁵ N
