Asatellite of mass m is in a circular orbit of radius r2 around a spherical planet of radius r1 made of a material with density p. ( r2 is measured from the center of the planet, not its surface.) use g for the universal gravitational constant. part a find the kinetic energy of this satellite, k. part b find u, the gravitational potential energy of the satellite. take the gravitational potential energy to be zero for an object infinitely far away from the planet.

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?
