Answer 1

Northward u=75.9 m/s V = 6.69 m/s K 725m Final Velocity of jetliner = 6:69 m/s(v) Initial v « « (u) = 75-9 m/s the distance (s) = 725 m So applying va utas a accelaration = v2_10² 25 So, the acelaration (6.69 – (75.9) be = 3.94 m/s2 South world 2x 725 44.76 – 5760.8 24 725 - - 3.94 m/s2 a
