1. The problem statement, all variables and given/known data A bead slides without friction around a loop-the-loop as shown in the figure below. The bead is released from a height h = 3.75R. (a) What is the bead's speed (V) at point A? Answer in terms of R and g, the acceleration of gravity. I don't have the picture it's in the book so I'll describe it. It's a downward slope that go's into a loop. 'A' is at the the top of the loop and R is the loop's radius. 2. Relevant equations a=v^2/r 3. The attempt at a solution Since it's perfectly parallel with the y axis, and therefor i assume a is 9.81, I get (gr)^1/2, but my webassignment program says that's wrong.
