According to the Guinness Book of World Records the longest home run ever measured was hit by Roy “Dizzy” Carlyle in a minor league game. The ball travelled 188 m (618 ft) before landing on the ground outside the ballpark. (a) Assuming the ball’s initial velocity was in the direction of 450 above the horizontal and ignoring resistance, what did the initial speed of the ball need to be to produce such a home run if the ball was hit in a point 0.9 m above ground level? Assume that the ground was perfectly flat. (b) How far would the
