A rock is thrown from the roof of a building with a velocity v_0 at an angle of alpha_0 from the horizontal. The building has height h. You can ignore air resistance.
Calculate the magnitude of the velocity of the rock just before it strikes the ground.
V=V_0 + at
X=V_0t + 1/2at^2
v_0(sin(alpha_0))-2(v_0)
The catch is that when i put the answer into the system, it told me that v_o and alpha_0 are not part of the answer. Any help is appreciated.
