can anyone help me out with a simple work problem?
say I lifted a bag of shingles that weighed 90 lbs from the ground to 6 feet in 5 seconds, then took 8 seconds to walk that bag to a scaffold which upon arriving to the scaffold it took me an aditional 3 seconds to put it from my 6 foot shoulder to the 6'6" scaffolding platform.
how much work would be involved?
(note: assume there is no aditional forces work on any part such as friction or wind)
