Consider the following measurements of planetary orbital period (years) and distance from the sun (AU). R (AU) 0.72 0.62 1.00 1.00 1.52 1.88 5.2 11.89 T (yrs) Assume a power law model: T = kRm where T-orbital period, R=distance from the sun, m=constant, k=constant Use the Method of Selected Points, employing the 2nd and 4th data points to determine values (and units) for the constants k and m.
