13. [-/2 Points] I DETAILS OBINPHYSS 2.P.016. I MY NOTES I ASK YOUR TEACHER PRACTICE ANOTHEF On aircraft carriers, catapults are used to accelerate jet aircraft to flight speeds in a short distance. One such catapult takes a 18,500kg jet from 0 to 68 rn/s in 2.6 5. (Assume the catapult acts in the positive horizontal direction. Indicate the direction with the sign of your answer where appropriate.) (a) What is the acceleration of the jet in m/sz? m/sZ What is the acceleration of the jet in 9's? :9 (b) How far does the jet travel while it is accelerating? :m (c) How large is the force that the catapult must exert on the jet? Z\" Need Help? 14. [-/2 Points] I DETAILS OBINPHYS8 2.P.023. MY NOTES ASK YOUR TEACHER PRACTICE ANOTHER On a highway curve with radius 42 m, the maximum force of static friction (centripetal force) that can act on a 1,323-kg car going around the curve is 8,127 N. What speed limit should be posted for the curve so that cars can negotiate it safely? :im/s Need Help
