A small rock of mass 0.150 kg is fastened to a massless string with length 1.20 m to form a simple pendulum. The simple pendulum is swinging on a vertical plane so as to make a maximum angle of 35.0 o with the vertical. Air resistance is negligible. (a) What is the speed of the rock at the instant that the rock passes through the lowest position. (b) What is the tension in the string at the instant that the rock passes through the lowest position?
