Asked by Sophia
A pitched ball is hit by a batter at a 45-degree angle and just clears the outfield fence, 98 m away. If the fence is at the same height as the pitch, find the velocity of the ball when it left the bat. Ignore air resistance.

how long is in the air?
hf=hi+Viv*time-1/2 g time^2
0=0+Vi*sin45*t-4.9 t^2
solve for t in terms of Vi
then horizontal equation
distance=vi*cos45*t put t in there, and solve for vi
