Homework Equationst=change in x over change in v.
The Attempt at a Solution
I know the equations for speed and velocity, but I can't figure out how to apply them to this problem. I made several attempts, which I erased. I don't want anyone to solve the problem for me, but I would really appreciate a list of steps and/or the directions for applying the formula.
Thanks in advance!
