If this person has a normal 8.00% ability to accommodate (increase) the power of his eyes, what is the maximum distance of objects he can see clearly in m with his contact lenses and with totally relaxed eyes? (Assume a lens-to-retina distance of 2.00 cm. If he can see very distant objects clearly, enter 'infinity'.)

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?
