A simple pendulum consists of a bob of mass 1.8 kg attached to a string of length 2.3 m. The pendulum is held at an angle of 30 Degrees from the vertical by a light horizontal string attached to a wall, as shown above.

1. Calculate the tension in the horizontal string.

2. The horizontal string is now cut close to the bob, and the pendulum swings down. Calculate the speed of the bob at its lowest position.
