Question
(11%) Problem 1: An aircraft carrier uses a device called a catapult to help accelerate jets to the speed needed for take off. The flight decks on these carriers have length d= 85 m. A jet with a mass of ml = 11370 kg can be accelerated from rest to a speed of v = 47 m/s by the end of the flight deck. Randomized Variables d-85 m m=11370 kg v47 m/s 33% Part (a) Select the correct symbolic expression for the magnitude of the average net force, FL, acting on the jet during its launch mv ial.

b) putting the values
FL = 11370*472 / (2*85) = 147743.1176 N
c) R= FL/mg = mv2/ (2d*mg) = v2/ (2dg )
R = 472/2*85*9.8 = 1.325
