If a 1500 kg car can accelerate from 35 km/h to 55 km/h in 3.8 s, how long will it take to accelerate from 55 km/h to 75 km/h? Assume the power stays the same, and neglect frictional losses(adsbygoogle = window.adsbygoogle || []).push({});

what I have tried so far:

55=35+a3.8

a=5.263 km/h squared

75 squared= 55 squared + 2(5.263squared)d

d=46.93

46.93=55+2.6315t

-8.067= 2.6315t

t=3.06 but the answer is obviously wrong
