Intergated chemistry/physics

A car is accelerated at a rate of 2.5 meters/second^2. If the starting speed is 5.0 meters/second, how many seconds will it take the car to reach a final speed of 27.0 meters/second?

  • Intergated chemistry/physics -

    (27-5)/2.5 = 8.8

  • Intergated chemistry/physics -

    V(final) = V(initial) + accel x time
    Vf = Vi + at
    Solving for t,
    t = (Vf-Vi)/a
    t = (27.0m/s-5.0m/s) / 2.5m/s^2 = 8.8 seconds
