PLZ I need your help with these questionsASAP.
1- A force of 6 lb is required tohold a spring stretched 8 in. beyond its natural length. How muchwork W is done in stretching it from its naturallength to 11 in. beyond its natural length?
W =.............. ft-lb
2- Suppose that 5 J of work is neededto stretch a spring from its natural length of 32 cm to a length of40 cm.
(a) How much work (in J) is needed to stretch the spring from 36cm to 38 cm? (Round your answer to two decimal places.)
.............J
(b) How far beyond its natural length (in cm) will a force of 30N keep the spring stretched? (Round your answer one decimalplace.)
.............. cm
