Compute each parts of given question:
Question: Two newly discovered planets follow circular orbits around a star in a distant part of the galaxy. The orbital speeds of the planets are determined to be 39.4 km/s and 62.5 km/s. The slower planet's orbital period is 8.03 years.
Part A: What is the mass of the star?
Part B: What is the orbital period of the faster planet, in years?
I need help to determine the orbital period of the faster planet, in years.
