4 Hidden Planet A planet present in our Solar system but never visible in the night sky, has an orbital period of 3.16 × 10^7 s. If the mass of the Sun is 1.99 × 10^30 kg at what distance (in kilometers) from the Sun’s center does the planet orbit? A. 97,200,000 km B. 150,000,000 km C. 265,000,000 km D. 391,000,000 km #6 Work done by friction A 2.52 kilogram disk slides across a level surface where the coefficient of kinetic friction is 0.150. If the disk slides 82.1 meters before coming to rest, what is the magnitude of the work done by the force of friction? Note that friction decelerates the mass, is directed oppositely to the displacement, and the work is negative in sign. A.148J B.221J C.304J D.442J
