Homework Statement
What is the minimum velocity required to throw a ball over a house with a pitched roof ( See attachment for the figure) You can choose the throwing point as needed
The Attempt at a Solution
(Choose throwing point standing near a and facing left) Assuming b is the hypotenuse of a right triangle and a-c is one side we can find the other side (let's call it d) using the Pythagorean theorem b^2 -(a-c)^2 = d
= -a^2 +2ac +b^2 -c^2
a is the maximum height of the projectile
a=(v^2sin^2θ)/2g
assuming d is the range
d=v^2sin(2θ)/g
I tried creating an equation forvfrom these equations , but it turned out to be too massive to even make a sensible answer.
Please help.
