Question

A 1 kilogram bead moves with constant total mechanical
energy on a frictionless wire track. The track is in a
vertical plane and consists of straight segments and
circular segments. For example, points B, F, G, H are on
straight segments. Points A, C, D, E are on circular track
segments. Point A is at the top of the track and point H
is the lowest point of the track.
The bead is shown initially at point C with a velocity 5.6
m/s down as represented by the velocity arrow. The
circular portion of track that includes points A, C, D has
a radius 3.2 meters.
The "direction key" shows eight arrow directions
labeled 1 to 8. To use the "direction key", consider the
