A 0.400-kg bead slides on a frictionless, curved wire, starting from rest at pt A in the figure below, where h = 1.50m. At point B, the bead collides elastically with a 0.600-kg bead at rest.
(i) Find the speed of the first bead just before it collides with the bead at rest.
(ii) Find the speed of the second bead just after the collision.
(iii) Find the maximum height the second bead rises as it moves up the wire.
