Total 0/1 ...If a truck traveling 38.0 km/h uniformly accelerates up to 55.0 km/h, what's its average speed in the process?

  • physics -

    It is the average of 38 and 55. I am sure you know how to calculate that.

    If it were not uniformly accelerating, the average speede could be something else between 38 and 55. .
