(3%) Problem 20: 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= 73 m. A jet with a mass of m = 11071 kg can be accelerated from rest to a speed of v = 45 m/s by the end of the flight deck. Randomized Variables d = 73 m m = 11071 kg v = 45 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. FL = mv 2d Correct! >33% Part (b) Calculate the numerical value of the magnitude of the force FL in Newtons? FL-153219.35 F = 1.532 x 105 Correct! 33% Part (c) What is the numerical value of the ratio R of the launch force FL to the jet's weight? R = 1.140 Grade Summary Deductions 0%
