Circular Motion A 1 Kg bead is confined to move on a vertical circle of radius 2 meters. There is no friction between the bead and the circular track. The bead has a speed of 10 m/s when at the top of the circle at point "A", and the total mechanical energy of the bead is assumed to be constant as it moves around the circle. Assume it takes the bead 0.62 seconds to go counter-clockwise from point "A" to point "B" each cycle. 10 m/s 2 m 30° Note: vector directions should be given as the "standard" angle with 0≤0 < 360 degrees Calculate the average speed (m/s) from "A" to "B" (based on the 0.62 seconds mentioned in the description).
