f a pronghorn antelope accelerates from rest in a straight line with a constant acceleration of 1.5 m/s2 , how long does it take for the antelope to reach a speed of 20 m/s?

  • physics -

    Given

    Vi = 0 m/s {rest}
    a = 1.5 m/s^2
    Vf = 20 m/s

    Vf = Vi + at
    t = Vf/a

    Vi cancels out

    ** Plug in and you should get the speed as 13.3 s
