Suppose that 6 J of work is needed to stretch a spring from its natural length of 32 cm to a length of 46 cm. (a) How much work (in J) is needed to stretch the spring from 37 cm to 41 cm? (Round your answer to two decimal places.) (b) How far beyond its natural length (in cm) will a force of 40 N keep the spring stretched? (Round your answer one decimal place.) cm
