If anyone can solve these two problems I will find something to give you.
1) A 160-lb man carries a 25-lb can of paint up a helical staircase that encircles a silo with a radius of 20ft. If the silo is 90ft high and the man makes exactly three complete revolutions, how much work is done by the man against gravity in climbing the stairs.
2) Suppose there is a hole in the can of paint in the above problem and 9lbs of paint is steadily leaking out of the can during the mans ascent. How much work is being done?
Hint: Use Line Integrals to calculate work.
