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 Previous A 30° Note: vector directions should be given as the "standard" angle with 0 ≤0 < 360 degrees Calculate the direction of the velocity of the bead at point "B". Enter the standard angle in degrees.
4. Two wheels (A and B) of equal mass and the same Iz roll down a hill without sliding and have the same kinetic energy. Partway down the hill, wheel B stops rolling and continues down the hill sliding (no rotation), but maintains the same kinetic energy as wheel A which continues to roll without sliding. Which wheel reaches the base of the hill first (assuming they travel the same path length)? wheel A (the one that rolls the whole way) wheel B (the one that starts sliding) they reach the hill base at the same time
