If it takes 4.00 J of work to stretch a Hooke's Law spring 10.0 cm from its unstressed length, determine the extra work required to stretch it an additional 10.0 cm


The extra work required in this situation would be an additional 4.00 J of work. This is because Hooke's law states that the force necessary to stretch the spring is directly proportional to the amount it is stretched; thus, if 4.00 J of work is required to stretch it 10.0 cm, then 4.00 J of additional work would be required to stretch it an additional 10.0 cm. The total work required to stretch the spring 20.0 cm from its unstressed length would therefore be 8.00 J.
