Question

Tiger Team 5 , an elite squad of slaves in Egypt, circa 2500 BCE, consists of 8 members

each of which is capable of pulling or pushing with a force of 1000 Newtons. They are

tasked with moving stone blocks up to the top level of one of the Pyramids in Giza

(approx. 140 meters high). Each block they are to move has a mass of 15,000 kg.

Assuming they pull the blocks up a ramp, with logs rolling beneath each block reducing

the effective rolling frictional drag coefficient to 0.02. What is the maximum slope of

the ramp they could pull these blocks up? How long would the ramp have to be for

them to raise the blocks to the top level? How much work would each member of the

team have to do to make this happen?
