A simple pendulum of length L=0.972m with a bob of mass m=45.8g is pulled aside until the bob is at a height L/4 above its equilibrium position. The bob is then released. Find the speed of the bob as it passes through a point where its height is L/7 above its equilibrium position. What is the angle the pendulum makes with the vertical at this point? Neglect any effects due to air resistance. 20 U₁-0--0- L Ah=+L lih
