One end of a light inextensible string is attached to a block. The string makes an angle of 60° above the horizontal and is used to pull the block in a straight line on a horizontal floor with acceleration 0.5 m/s². The tension in the string is 8 N. The block starts to move with speed 0.3 m/s. For the first 5 s of the block’s motion, find

1. the distance travelled,
2. the work done by the tension in the string.
