In the 1970 National Basketball Association championship, Jerry West made a 60ft shot from beyond half court to lead the Los Angeles Lakers to an improbable tie at the buzzer with the New York Knicks. Suppose West threw the ball at an angle of 45 above the horizontal. The basket is 10ft from the court floor. Neglecting air resistance, estimate the initial speed v0 of the ball. (The Knicks won the game in overtime.)
