A mountain climber practices his technique in a mountain climbing school by balancing while suspended by two ropes attached to the ceiling. As shown by the figure, the left rope makes an angle of 60 degrees with the horizontal ceiling and the right rope makes an angle of 30 degrees with the horizontal ceiling. If the right rope has tension T1=322 N, what is the weight of the mountain climber?

A bucket that has a mass of 25 kg when filled with sand need to be lifted to the top of a 10 meter tall building. You have a rope that has a mass of 0.4 kg/m that must be secured to the bucket. It takes 1 meter of rope to secure the bucket. Once the bucket reaches the top of the building it only has mass 14 kg because there was a hole in the bottom and sand was leaking out at a constant rate while it was being lifted to the top of the building. Find the work done lifting the bucket (sand and rope) to the top of the building.
