Suppose that 3 J of work is needed to stretch a spring from its natural length of 32 cm to a length of 52 cm. (a) How much work (in J) is needed to stretch the spring from 40 cm to 44 cm? (Round your answer to two decimal places.) (b) How far beyond its natural length (in cm) will a force of 25 N keep the spring stretched? (Round your answer one decimal place.) cm
