Homework Help: Velocity vs. time graph

  1. Jun 6, 2005 #1
    the x axis is in minutes, the y axis is in m/min.

    I know that the acceleration = the slope.

    should my final answer be in m/min^2 ?

    or should acceleration always be in m/s^2 ?

    or does it not matter? :confused:


    thanks :smile:

    There is nothing wrong with m/min^2 aside from it not being standard. Your best bet is just graphing it against seconds by converting your data from minutes to seconds BEFORE graphing.

    yeah if I was taking down the data I would.
    This is just a question on an assignment, where the graph is given.

    Its an easy question, but after I did it the answer just doesnt look right to me, so I figured I'd ask.

    acceleration has been in m/s^2 everytime I have come across it.

    That is because meters and seconds are the SI units for time and distance. It is the international standard.

    As whozum said, no problem at all. The important thing is that the units are distance over time squared. Remember that you can always convert between the standard m/s^2 and the non-standard m/min^2.
