1. The problem statement, all variables and given/known data A bead slides without friction around a loop-the-loop (Fig. P8.5). The bead is released from a height h = 3.30R. (a) What is its speed at point A? Answer in terms of R and g, the acceleration of gravity. (b) How large is the normal force on it at this point if its mass is 4.40 g? 3. The attempt at a solution Having some trouble with both parts. Thanks.
