Two skaters, one with mass 68 kg and the other with mass 47 kg, stand on an ice rink holding a pole of length 8.8 m and negligible mass. Starting from the ends of the pole, the skaters pull themselves along the pole until they meet. How far does the 47 kg skater move?
I thought this was just a center of mass question, but the answer I get is apparently wrong.
search (with 3/4 of the cube in the water and 1/4 in the oil.What is the density of the cube? if the oil-air is open to the air, the cube is 40cm long,and the water-oil boundary sits 0.25m below the oil-water boundary what is the guage pressure at the bottom of the cube?)
like 9 or somethin
