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 traveled 188 m (618 ft) before landing on the ground outside the ballpark.

1.Assuming the ball's initial velocity was 47 ∘ above the horizontal and ignoring air resistance, what did the initial speed of the ball need to be to produce such a home run if the ball was hit at a point 0.9 m (3.0 ft) above ground level? Assume that the ground was perfectly flat.

2.How far would the ball be above a fence 3.0 m (10 ft) high if the fence was 116 m (380 ft) from home plate?
