Homework Statement
A canon is burried on a hillside, so the barrel is exactly at the height of the surface. The hillside creates angle theta with vertical, where 0 degrees < theta < 90 degrees. A canonball is fired with speed v_0 perpendicular on the hillside. The angle between velocity_0 and horizontal also has angle theta. g is 9.8 and there is no air resistance.
a) Find the vertical distance from the firingpoint to the point where the canonball again has the same height as when it was fired.
b) Find the horizontal distance from the firingpoint to the impact location on the hillside.
This is the exact text translated from my language. And sorry about my lack of paint skills.
Homework Equations
How am I supposed to find the distance when I have no variables?
The Attempt at a Solution
vox = v0*cosθ
voy = v0*sinθ
y = voy*t-1/2*g*t2
y = 0 = voy*t2-1/2*g*t2 = t2(voy-1/2*g*t2)
t2=0 and t2=(2*voy)/g
R = vox*t2
This is my first time using this forum, so I hope this is the style people want to see it in.
