Question
A 3.0g bead has been threaded onto a vertical, frictionless, circular hoop with a 20cm
radius. The bead is released from rest at 25º below the vertical.
(a) Find the speed of the bead when it is 70° below the vertical.
(b) Using the free-body diagram technique, find the normal force acting on the bead and the
radial and tangential components of its acceleration vector when it is 70º below the vertical.

So far, I have only come up with an equation where the velocity is defined as
a = (V^2)/R
aR = V^2
V = √(aR)
Need help relating angle and mass to the resultant acceleration of radial and tangential acceleration.
