A small block of mass ?m is placed halfway up on the inside of a frictionless, circular loop of radius ?,r, as shown. The size of the block is very small compared to the radius of the loop. Determine an expression for the minimum downward speed ?minvmin with which the block must be released in order to guarantee that it will make a full circle.
