An 80 kg man carries a pail of water weighing 10 kg up a helical (spiralling) staircase with radius 6 m. The man makes exactly three complete revolutions and reaches a height of 30 m. Suppose a total of 2 kg of water leaks steadily during the man’s ascent. Express the work done by the man against gravity g ms^-2 as a line by writing down the vector field F and the vector equation of the curve C. Evaluate the work done by computing this line integral.
blood splatters across my foolscap before i slump forward on my table in an unconscious heap. i still have my position paper undone because my group mates (a) are incapable of contributing their fair share towards it (b) refuse to do their fucking bit and just want to feed off my effort. again. i hope they get monstrous ulcers in their mouths and horrendous blisters on their feet.
our day will come.
