I know how to calculate acceleration and stuff, but the wording of this question confused me:
"With a time of 6.92s, Irina Privalova of Russia holds the women's record for running 60m. Suppose she ran this distance with a constant acceleration, so that she crossed the finish line with a speed of 17.34m/s. Assuming she started at rest, what was the magnitude of Privalova's average acceleration?"
So what I was thinking is to just use the equation for average acceleration (a=Vf-Vi/Tf-Ti). But what confused me was where they gave us the information that she ran 60m and the wording of the question (what was the magnitude of the acceleration). How would I go about to solving this?
