Asked Feb 15, 2019

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. Assuming that the ball's initial velocity was 45∘ 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 1.0 m (3.3 ft ) above ground level? Assume that the ground was perfectly flat.

Step 1

The expression for the velocity is,

Step 2

Here, the vector ** v** is the velocity of the ball,

The expression for time taken for the ball to land is,

Step 3

Here, *t* is the time taken for the ball to land and *s* is the horizontal range of the ball.
