    Help with average velocity during a time interval

    Excellent. Thank you very much. I was over thinking this one. Just a quick question to confirm what the derivative is used for. I believe it is used to find instantaneous velocity. So, if the question asked me to find the velocity at a certain point, t=3, then I would substitute 3 for t into...

    Help with average velocity during a time interval

    Homework Statement The position of a particle in meters moving along the x-axis is given by: x=21+22t-6t^2 Calculate the average velocity of the object in m/s during the time interval t=1s to t=3s. Homework Equations x=21+22t-6t^2 t=3 ; t=1 v avg. = Xf - Xi/Tf - Ti = Δx/Δt don't...
