Homework Statement
"Supposing that at perihelion a comet is 1 Au from the sun and its speed at that point is 200km/s( in a frame of referance in which sun is stationary). Find its mean PE and KE to one sig digit. Does it satisfy the virial theorem?
Homework Equations
K= .5mv^2
U=-GMm/r
Virial theorem:
The Attempt at a Solution
I know how to calculate U and K, and I know that at perihelion the V is at max, but will the K and U I find be the mean?
