The Longest Home Run. 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. (a) Assuming the balls initial velocity was in a direction 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. (b) 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?

ANSWER:Step 1 of 3
Range of the projectile (x)= 188 m
= 45°
(a)
To found initial velocity
The ball is hit 0.9 m above the ground level
Horizontal component of velocity
=
Vertical component of velocity
=
Formula
y = -
-0.9 = - ------(1)
y is above the ground level
