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...
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
