An aircraft carrier uses a device called a catapult to accelerate jets to the speed needed for take off. the flight decks on these carriers have length d = 84 m. a jet with a mass of m = 13317 kg can be accelerated from rest to a speed of v = 53 m/s by the end of the flight deck.

a. select the correct symbolic expression for the magnitude of the average net force, fl, acting on the jet during its launch.
i. fl=mv/d
ii. fl=mv^2/2d
iii. fl=mv/2d
iv. fl=mv^2/d
v. fl=mvd
vi. fl=v^2/2d

b. calculate the numerical value of the magnitude of the force f in newtons?
c. what is the numerical value of the ratio r of the launch force fl to the jet's weight?
