You have been commissioned by Pharaoh Khufu to oversee the construction of the Great Pyramid of Giza. To build the pyramid, large stone blocks are pulled up the side of the pyramid by a skilled workforce of ancient Egyptians using a pulley system, shown to the right. Each stone block weighs 2,268 kg and the coefficient of kinetic friction between the block and the side of the pyramid is 0.6. The pyramid is built using an incline of 52 degrees. Each worker is capable of pulling with a constant force of 300. The stone block is initially at rest and it's accelerated up the inclined plane a distance of 190 meters in 26 seconds.
A. Calculate the net acceleration on the stone block. (0.56 )
B. Calculate the net force on the stone block. (275 )
C. Calculate the force of tension in the rope being pulled by the workers. (27,000 )
D. Calculate the number of workers pulling on the rope. (90 workers)
