Design a device that will knock a block of wood a distance of 5 meters. this was the challenge in science class. ben and sam designed a pendulum to move the wood block. their first design moved the block about 1.5 meters. they rebuild their pendulum and changed the mass of the pendulum bob. after the changes, the boys knocked the block of wood 4 meters, 6, meters, and finally 8 meters. the average distance the block moved after the final changes to the pendulum was 6 meters. the boys won the design challenge. building the pendulum is which step in the solution process
