Question

A bead slides on a wire, which is in a vertical plane, as shown in the diagram. Gravity acts in the -y direction (down). The bead starts at A and moves to the right with an initial velocity v. The wire is frictionless between A and D and also 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.  

Problem 3 + 0 + A bead slides on a wire, which is in a vertical plane, as shown in the diagram. Gravity acts in the -y direction (down). The bead starts at A and moves to the right with an initial velocity v. The wire is frictionless between A and D and also 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. True Between D and F, the speed decreases, then increases Less than The total energy of the bead at B is ... the total energy at D Equal to The speed at B is ... the speed at F False The bead's potential energy at A is greater than its potential energy at G Due in 10 hours, 59 minutes Submit Answer Incorrect.

Answer 1

F 1) Between DaF speed decreases , then Pococoses. – True. from 0 to € there will be decrease in Konetic energy due to friction but Eto [ Kinetic energy increase & due to converfion of potential energy to Kinetic. 2) 3) The total energy at Big greater equal to the total energy at D pence wire is frictionle Be between Bto.so total mechanical energy is conserved. The speed at B is more (greater than) Bpeed at F pince total mechanical energy at B A D are equal but o to F due to fiction there pe logg in mechanical energy so it 8 speed will be le of at F. The bead's potential energy at APB greater than to potential energy at G. -false. potential energy PB Bolely due to position /configuration of object. both Ad a hove Game height Bo their potential energies are equal
