are you sure that conservation of energy is the correct way to solve the problem? because that just seems a little too easy. Is there another way to do it so we compare the results

How about an infinitely small amount of energy? Would that work too

ok here is the corrected diagram. I know about Cartesian coordinates and yes that's what i use but i am a dyslexic so sometimes i get things switched around.

here is a diagram of the situation

Are you sure that's all there is to it? Because if we give it just enough velocity to reach the top of the circle (0,1) then would it not just stay at rest at that point theoretically? The problem states that it must get past its original position of (1,0). We must find the absolute minimum...

We must find the initial velocity such that will be able to get past point (0,1) thus it will be able to get back to ( and past) its original position of (1,0)

Im sorry, i was mistaken in my coordinates. The original coordinates are (1,0). It is pushed with a downward force when it is released. .

Homework Statement A ball of mass M is attached to a 1.0m pole that is pivoted on the wall at point (0,0); such that it can take the path of a circle. The ball is initially held up at rest at the point (1,0). It is then pushed with a downward force. What minimum initial velocity must it have...
