A 215 g particle is released from rest at point A (the middle of one side) inside a smooth hemispherical bowl of radium 30.0 cm. Calculate the gravitational potential energy at A relative to B. (B is in bottom-middle of the bowl)
Ok, so PE_g=mgh. How would I find the height of A? If necessary, I could scan the diagram shown in the book.
PS I'm still stuck on my other question if you have time :)
What is the radius? It is a hemisphere.
ok, I made a similar image on paint
now, the distance from A to B is not the same as the radius, right?
