all of the above
A pro cyclist is climbing Mount Ventoux, equipped with a 150-millimeter-diameter
chainring and a 95-millimeter-diameter sprocket. If he was pedaling at a rate of 90 revo-lutions per minute, find his speed in kilometers per hour. (1 km 5 1,000,000 mm)
A large spherical gas cloud of radius = 5 x109 km has a mass = 2.4 x1030 kg, and is spinning to make one revolution in 60 years (i.e. Earth years, each of 365 days of 24 hours each). Due to gravity, the cloud gets smaller to a radius = 1.2 x106 km. What will be its period of rotation in minutes?
