1 pt The figure below shows a bead sliding without friction along a curved wire in a vertical plane. A H D C B The bead slides starting from rest at position A on the fric- tionless wire. The direction of the gravitational field is in the -y direction (toward the bottom of the page). The acceleration in the y-direction at B is ... zero. 20.
