The quantities v, k, u, and l all represent physical quantities characterizing the orbit that depend on radius r. indicate the exponent (power) of the radial dependence of the absolute value of each. express your answer as a comma-separated list of exponents corresponding to v, k, u, and l, in that order. for example, -1,-1/2,-0.5,-3/2 would mean v∝r−1, k∝r−1/2, and so forth.

Aplayground merry-go-round has a radius of 4.6 m and a moment of inertia of 200 kg-m2 and turns with negligible friction about a vertical axle through its center. a child applies a 26.0 n force tangentially to the edge of the merry-go-round for 15.0 seconds. if the merry-go-round is initially at rest, how much work did the child do on the merry-go-round?
