Can someone help me with the coding for this problem on MATLAB for problems a,b and c please? Thank you, and also please label each code and output with the correct question.

Spring Problem Consider a spring with the left end held fixed and the right end free to move along the x-axis. We assume that the right end of the spring is at the origin x = 0 when the spring is at rest. when the spring is stretched, the right end of the spring is at some new value of x greater than zero. When the spring is compressed, the right end of the spring is at some value less than zero. Suppose that the spring has a natural length of 1 ft and that a force of 10 lb is required to compress it to a length of 0.5 ft. Then, it can be shown that the work, in ft lbf performed to stretch the spring from its natural length to a total of n ft is equal to the integral of 20x over the interval from 0 to n-1 (a) Use MATLAB to determine a symbolic expression that represents the amount of work necessary to stretch the spring to a total length of n ft. (Work is the integral of force times the differential of position) (b) What is the amount of work done to stretch the spring to a total of 2 ft? (c) If the amount of work exerted is 25 ft lbf, what is the length of the stretched spring? Length x=0 x>0
