These 2 questions are confusing me, I have some idea about what to do, can someone help? Question 1 1. The problem statement, all variables and given/known data Consider a circular track with a radius of 200 meters, suppose it takes 2 minutes to run from her starting point to the opposite side of the track. What is the magnitude of her average velocity over this 2 minute interval? What is her average speed over the same interval? 3. The attempt at a solution I did 400m/120s and got 3.33 m/s, and for speed 400m/120s = 3.33 m/s (should I be putting significant figures also or something?) Question 2 1. The problem statement, all variables and given/known data Derive Vf^2=Vi^2+2ad 2. Relevant equations (I think this is equation for velocity of an object) 3. The attempt at a solution I thought that you would treat it like a derivative and comes out to 2Vi+2, but I got it wrong.
