Make a value scalar or vector?

  1. Oct 9, 2007 #1
    1. The problem statement, all variables and given/known data
    no real problem statement, this isn't an equation

    2. Relevant equations
    same as above...

    3. The attempt at a solution
    absolutely none --

    Please read this

    I am nowhere near the level of anyone on this board, I'm having trouble with beginning high school physics homework, and just couldn't figure it out on my own.

    the problem is that I have a table filled with data of everyone in class, and how far we threw a tennis ball in yards, how long the throw took in seconds, and the overall speed (or velocity) of the ball.

    problem is, it's asking me a question I dunno how to answer --

    "How do you make it scalar or vector?" this is in relation to the Velocity.

    any ideas on this?

    thanks in advance, and sorry I didn't/couldn't use your format.

    Then you must understand the difference between scalar and vector.

    Vector is a quantity with direction and scalar is only a quantity.
    Velocity is a vector, Speed is a scalar.
