Suppose that 4 J of work is needed to stretch a spring from its natural length of 26 cm to a length of 43 cm. (a) How much work is needed to stretch the spring from 30 cm to 35 cm? (Round your answer to two decimal places.)
J
(b) How far beyond its natural length will a force of 10 N keep the spring stretched? (Round your answer one decimal place.)
