2minutes 20 secinds=3.5 rounds
circumfrence=2pieR
displacement=7x22/7xr
=22r
So the displacement will be 22r
Nope, displscement is a vector.
displacement= ending position-starting position.
As I calculate, he is opposite his starting position, or 2R, in the direction opposite the starting point. In polar coordinates, the displacement is
2R@180
