Could anyone help me with this
given: g =9.8, length = .7 m , postion: 40 to 20 degrees
9. This problem involves the law of conservation of mechanical energy (potential into kinetic). You might use the available virtual devices to help set it up and compute the required quantities. Suppose that the initial angular position of the pendulum is 40°. Then, the pendulum is released, and it passes the angular position of 20° from the equilibrium. When the pendulum is at the position of 20° calculate: The tangential velocity Centripetal acceleration Tangential acceleration Angular velocity Resultant acceleration. Angular acceleration
