On aircraft carriers, catapults are used to accelerate jet aircraft to flight speeds in a short distance. One such catapult takes a 17,500-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.)

How far does the jet travel while it is accelerating? in meters

17500 kg is irrelevant

acceleration is change in velocity/change in time =    65/2.7 = 24.07 m/s2

vf

xf = x0 + vo t + 1/2 at^2

   = 0    +  0 * t     +  1/2 (24.07)(2.7^2 ) = 87.75 meters

A jet aircraft with a mass of 4,375 kg has an engine that exerts a force (thrust) equal to 60,900 N.

How far does the jet travel during the 9 s?
