Sorry I didn't explain this better, this was not given as a mathematical problem, instead it was a problem which we were expected to try and talk through. No numerical values were given, making it completely impossible to actually determine the mass of pluto. We were simply expected to...

Homework Statement On June 22, 1978, James Christy made the first observation of a moon orbiting Pluto. Until then, the mass of Pluto was not known, but with the discover of its moon, Charon, its mass could be calculated with some accuracy. Explain. 2. The attempt at a solution "By...

Oh I see, because if I was to divide 7.7m by 9.8m i wouldn't be left with a unit. Instead, I suppose I should just divide 59m^2 by 9.8m, making H=6.0m?

Homework Statement A skier starts from rest at height H on the side of a valley. The other side of the valley rises to a rounded peak at 4.0m. Assuming the skier goes down one side of the valley and up the other, what is the maximum value of H for which the skier remains in contact with the...
