How much distance did she travel while slowing down? Av, Qargi Vis = Vis + a, At Si= si + vir At + ja, (A1) ve = vi? + 2a, As

Answer 1

Initial veloutyu-gomph = 35.763 m/s Final Vebery V somph = 29.352 m/s Acelaration as a = 35763 = 350763 - 22:350_31352m) ve u taas., s = distance मर 35.763 2 . 3 4. s = 35.763 - 22.352 = 116.25m 2x3.352
