A pitched ball is hit by a batter at a 45° angle and just clears the outfield fence, 90 m away. Assume that the fence is at the same height as the pitch and find the velocity of the ball when it left the bat. Neglect air resistance.

The range of projectile is
L=(v0)^2•sin2α/g.
If α=45 degr, sin2α = 1, then
L=v0^2/g.
v0=sqroot(L•g)= sqroot(90•9.8)= 29.7 m/s
