how long does a car with an acceleration of 2.0 m/s^2 take to go from 10m/s to 30m/s?and its solution

  • physics -

    if that is constant acceleration,

    a = (v-u)/t

    plug inthe numbers and you get the time elapsed.

  • physics -

    GIVEN:
    Vf=30m/s
    Vi=10m/s
    a=.0m/s^2

    REQUIRED:
    t=?

    SOLUTION
    t=(Vf-Vi)/a
    =(30m/s-10m/s)/2.0m/s^2
    t=10s
