Homework Statement

see the diagram two posts below this.
A bead slides on a wire, which is in a vertical plane, as shown in the diagram. Gravity acts in the -y direction. The bead starts at A, moving to the right with an initial velocity v. The wire is frictionless between A and D and between F and G, but there is friction between D and F. (For each statement select True, False, Greater than, Less than, Equal to, or Not enough information to tell.
1. The speed at A is ______ the speed at C
2. True or False: Between C and D, the speed increases, then decreases
3. The bead's kinetic energy at D is _____ its kinetic energy at F
4. The total energy of the bead at A is ______ the total energy at B

Homework Equations

The Attempt at a Solution

1. less than because potential energy is converted into kinetic
2. false because I can't see why it would decrease
3. less than because potential energy is converted to kinetic
4. equal to because energy is conserved and this part is frictionless

Would be easier if I could access the diagram.. the link requires an account on that site.

sorry everyone here's the new diagram
