Homework Statement
A person standing on top of a hemispherical rock (a dome rock) of Radius R kicks a ball (initially at rest on top of the rock) to give it horizontal velocity Vx
A. What must be it's minimum initial speed if the ball is never to hit the rock after it's been kicked?
B. With this initial speed. ow far from the base of the rock does the ball hit the ground
Homework Equations
Xf = V0 + VxiT + 1/2AxT
Vx = VCos(theta)
Vy = VSin(theta)
The Attempt at a Solution
That's the thing I don't even know where to begin. I don't understand what it wants me to find. It gives no variables whatsoever!
