Find the velocity of the ball when it left the bat. assume the fence is the same height as the pitch.?

Question

A pitched ball is hit by a batter at a 47 degree angle. It just clears the outfield fence, 92 meters away. the acceleration of gravity is 9.8 meters per seconds square.

Answer 1

got 3 variables, so need 3 equations
(sin47v)^2=19.6s
s=4.9t^2
92=(cos47v)2t
do a bunch of solving to get t=2.245,s=24.67, and v=30.06
so 30.06m/s is the answer
check it! it works!!!
if you want all of the work or have questions send me an email

Answer 2

inversly proportional to the strength in ft/lbs minus the visual accuity in candlepower/m(200)C/ distance of the ball from the sun@ perigree( battery life of radar gun)~ of the fat guy in the bleachers.
