A baseball pitcher throws his curve ball at 80 mph with a rotational speed of 1800 rpm. The ball has a mass of 5 oz and a 9 in. circumference. Estimate how much this pitch will break as it travels a distance of 55 ft in a spring game in New York, when the air temperature is 50°F. What is the break in a summer game when the temperature is 90°F? In your calculation, assume that the rotation axis of the ball is vertical.
