Suppose that 2 J of work is needed to stretch a spring from its natural length of 28 cm to a length of 41 cm. (a) How much work is needed to stretch the spring from 36 cm to 46 cm? (Round your answer to two decimal places.) (b) How far beyond its natural length will a force of 30 N keep the spring stretched? (Round your answer one decimal place.)
