Oops, I made a mistake. Thanks for pointing it out. So I have a) True b) Sorry, I'm a bit confused. The formula for kinetic energy is = 1/2 mv^2. So that mass at D is the same as at F so that doesn't change. For velocity, it will decrease because of friction? Or the velocity will increase...

I can't seem to be able to upload them so here they are: a) Between A and B, the speed increases. b) The bead's kinetic energy at D is ... it's kinetic energy at F. c) The speeds at D and E are equal. d) The total energy of the bead at B is ... the total energy at D.

Homework Statement 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...
