Baseball: The bases on a baseball
diamond form a square 90 ft on a
side. The pitcher's plate is 60 ft
6 in. from the back corner of
home plate.

a. About how far is the pitcher's
plate from second base?

b. A line drive is 10 ft high when it
passes over the third baseman,
who is 100 ft from home plate.
At what angle did the ball leave
the bat? (Assume the ball is 4 ft
above the ground when it is hit.)
