A plane travels 5.1 102 m while being accelerated uniformly from rest at the rate of 4.9 m/s2. What final velocity does it attain?

  • physics -

    I assume that the distance you were trying to write is D = 510 m. You should have written it as 5.1*10^2 m

    The acceleration rate is a = 4.9 m/s^2

    Vmax = sqrt(2a*D) = 70.7 m/s
    = 254.5 km/h
    = 158 mph
