A pendulum is launched in two different ways A pendulum is launched in two different ways. During both launches, the bob has an initial speed of 3.0 m/s. On launch 1, the speed is up On launch 2, the speed is down Which launch will cause the pendulum to swing the largest angle from the equilibrium position on the left side?
