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

Acompany that makes shopping carts for supermarkets and other stores recently purchased some new equipment that reduces the labor content of the jobs needed to produce the shopping carts. prior to buying the new equipment, the company used 6 workers, who produced an average of 79 carts per hour. workers receive $16 per hour, and machine coast was $49 per hour. with the new equipment, it was possible to transfer one of the workers to another department, and equipment cost increased by $11 per hour while output increased by four carts per hour. a) compute the multifactor productivity (mfp) (labor plus equipment) under the prior to buying the new equipment. the mfp (carts/$) = (round to 4 decimal places). b) compute the productivity changes between the prior to and after buying the new equipment. the productivity growth = % (round to 2 decimal places)
