The typical baseball diamond is a square 90 ft 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.)

For a typical day in your life, from the time you get out of bed in the morning to the time you climb back into your
bed at night, estimate the following:
distance =
displacement =
11.
Think of the total distance you have covered in your lifetime. Is it
possible for you to move in some direction to reduce this distance to zero?
12.
If so, where would you go? If not, why not?
13.
Is it possible for you to make your lifetime displacement equal to zero?
14.
If so, where would you go? If not, why not?
