The equation to use:V² = U² + 2*a*s0 = 81.9² +2*949*a0 = 6,707.61 + 1898a a = -6707.61/1898a = -3.53The acceleration is 3.53m/s² and the negative sign indicates that it is to the north ( opposite of south, which we took as positive)... Show More

vf squared = vi squared + (a * distance)* vf is 0 – the plane has come to rest0 = 81.9^2 + (a * 949) 0 = 6707.61 + 949a– 6707.61 = 949aa = – 7.07 m/ s^-2a = 7.07 m/s^-2 , north... Show More

d = 0.5 at^2 + Vo*tVo = 0 second term drops outv = at81.9 =ata = 81.9/t949 = 0.5 * 81.9 /t * t^2949 = 81.9 tt= 11.59 a = 81.9/11.59a =7.07 m/s^2... Show More
