A certain car is capable of accelerating at a rate of +0.60 m/s2. How long does it take for this car to go from a speed of 20 mi/h to a speed of 65 mi/h?

  • physics -

    acceleration = change of speed / time
    but make sure the units are consistent.
    change of speed
    = (65-20) mph
    =x m/s (find x)
    0.60 = x/t
    or
    t=x/0.6 seconds
