The typical baseball diamond is a square 28m long on each side.
Suppose a player hits a homerun and makes one complete trip from
home plate, around the bases, and back to home plate.
Complete the table by finding the player's distance and
displacement as he rounds the bases. Include the proper units. All
angles are right angles. (Hint: You may need Pythagorean’s theorem
for 2nd base.)
