According to the Guinness Book of World Records, the longest home run ever measured was hit by Roy "Dizzy" Carlyle in aminor league game. The ball traveled 188 m (618 ft) before landingon the ground outside the ballpark.
a) Assuming that the ball's initial velocity was 45° above the horizontal and neglecting air resistance, what does the initialspeed of the ball need to be to produce such a home run if the ballis hit at a point 1.0 m(3.3 ft) above ground level? Assume that the ground was perfectly flat.
b) How far would the ball be above a fence 2.9 m (9.5 ft) inheight if the fence was 115 m(377 ft) from home plate?
