Randy is a famous pitcher in Long Island High School. His
average throwing distance is 35 yards. However, his coach was
analyzing Randy’s throwing angle and figuring how he had a bad
habit to unconsciously lift his arm earlier than he was supposed to
do. Coach trained Randy for his new strategy and measured his
throwing distance that turned out to be...
