If a car goes from 0 to 100 mph in six seconds with constant acceleration, what is that acceleration?

  • calculus 2 -

    let the acceleration be a
    then
    v = at + c
    when t=0, v=0 , so c = 0

    v = at
    when t=6 , v = 100
    100 = 6a
    a = 100/6 = 50/3

    the acceleration is (50/3 mph) / sec
