(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

A comet passes the sun at a distance of closest approach R = 6 * 10^8 m and speed 8 * 10^5 m/sec. How long will it take to travel 80 degrees around its orbit from the point of closest approach.

2. Relevant equations

omega = velocity / radius

3. The attempt at a solution

Since we can get omega from the above information, I should only have to integrate omega and set that equal to 80 degrees (or 4/9 pi radians)

omega = 8 * 10^5 / (6 * 10^8) or 1/750

the integral of this makes 1/750t and set that equal to 4/9 pi radians so,

t = (750 * 4 * pi)/9

t = 1047.2 seconds

I am not sure if this is the proper way of writing this equation and confirmation would be appreciated. Thanks in advance.
