Question

While watching a softball game you see a play that makes you wonder how fast a fielder can react to a hit, run to the fence, and leap up to make the catch. In this play, the batter hits a ball when it is barely off the ground. It looks like it will be home run over the left center field wall which is in a distance D= 215.0 ft from home plate. As soon as the ball is hit, the left fielder runs to the wall, leaps high, and catches it just before it clears the top of the wall with height h= 12.0 ft . You estimate that the ball left the bat at an angle of =30°.

Explanation / Answer

. It looks like it will be home run over the left center field wall which is in a distance D= 215.0 ft from home plate. As soon as the ball is hit, the left fielder runs to the wall, leaps high, and catches it just before it clears the top of the wall with height h= 12.0 ft . You estimate that the ball left the bat at an angle of =30°.

time to have y component=12ft=u2sin2300/2g

which gives u=32SQRT3

ALSO TIME =(SQRT3)/2

NOW VELOCITY OF  left fielder =215/(SQRT3)/2
