from solid sphere, solid cylinder and thin-walled cylinder.All three start from the same position and they all have the same kinetic energy
a) which oblect will go the farthest
b) does the result depend on the mass, radius of the object

a) solid sphere
b) no

See if you can figure out why. The clue is how much of the available energy (from potential energy loss) goes into ration. The fraction that goes into roation depends only upon shape and how the mass is distributed, not size or total mass.
