Plot a graph of the (√ ) square root of length ( vs ) the time for one oscillation (T). Square root all the length first on the calculator and get the values B4 u plot the graph.
One the X axis put the values of for time and on the Y axis put the values of √ square root of length.

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?
