I'm having a bit of trouble with this problem.
The distance D is the distance in millions of miles from the sun, and P is the period in years it takes to revolve one time around the sun.
D = 92.9
P = 1.0
I know that the formula for angular velocity is: omega = theta/t, with t being the time
and also that the linear speed is: v = radius*omega
also that 1 revolution is 360 degrees or 2pi
I think the problem I'm having though is with unit conversion. There are problems for other planets too, but if I can get help with just one, I can figure the rest of them out.
