Homework Statement


A baseball leaves a bat at 45m/s at an angle of 36.90° above horizontal. At the point of impact with the ball, the ball is 1.000m above ground level, and as it clears the fence it is back down to 11.00m above ground level. How far is home plate from the fence at this point?
θ=36.90°
v=45m/s
g= -9.800m/s2


Homework Equations


R= (2v2sinθcosθ)/g

You have to make an attempt at the problem before we can assist you.

Hint: Determine how long, timewise, it takes for the ball to reach the fence.

Also, your formula is not applicable for this problem because the fence is not 1 meter tall.
