A construction crane lifts a 100-lb bucket originally containing 140 lb of sand at a constant rateThe sand leaks out at a constant rate so that there is only 70 lb of sand left when the crane reaches a height of 50 feetHow much work is done by the crane?Please show al explanation! Thanks!
Constant rate so calculus not necessaryStarts by lifting 240 lb, ends by lifting 170 lb; so average is 205 lb lifted by 50 ftWork done is mgh Now you finish it off Regards - Ian P.SWho is al ?
That is so impossible I can't even begin to comprehend how you got that idea in your headThe only way pregnancy is possible in that bath is if you brought that guy in and proceeded to have sex with him.
