Callisto is an ice-covered moon and has no inner or outer activity and is considered basically geologically dead. Ganymede has rocky core and shows signs of tectonic activity, including long cracks in the crust and regions of young surface terrain.

Answer:
Part i)
h = 5.44 m
Part ii)
h = 3.16 m

Part i)
Since the ball is rolling so its total kinetic energy in this case will convert into gravitational potential energy
So we have
here we know that for spherical shell and pure rolling conditions
Part b)
If ball is not rolling and just sliding over the hill then in that case
