A bead slides without friction around a loop_the_loop (see figure below). The bead is released from rest at a height h = 3.80R.

What is its speed at point A? (Use the following as necessary: the acceleration due to gravity g, and R.)
V=__

How large is the normal force on the bead at point A if its mass is 4.10 grams?
magnitude=__
Direction=downward
