2. A bead slides without friction on the loop–the–loop track below. The bead is released from rest at a height h = 4R where R is the radius of the circular section of the track.

(a) Using energy considerations, find the speed of the bead at the highest point of the circular section A.

(b) Determine the radial component of the equation of motion for the bead at point A.

(c) Hence calculate the normal reaction force on the bead at point A if the bead has mass 3.0 g. (Assume g = 9.8ms−2)
