A satellite has a mass of 5987 kg and is in a circular orbit 4.66 × 105 m above the surface of a planet. The period of the orbit is 1.6 hours. The radius of the planet is 4.67 × 106 m. What would be the true weight of the satellite if it were at rest on the planet’s surface?

Asolid cylinder and a cylindrical shell have the same mass, same radius, and turn on frictionless, horizontal axles. the cylindrical shell has light-weight spokes connecting the shell to the axle. a rope is wrapped around each cylinder and tied to blocks of equal masses that are held the same height above the ground. both blocks are released simultaneously. the ropes do not slip. which block hits the ground first? or is it a tie?
