1.The potential energy, E, stored in a spring as a function of its compression,x

Question

1.The potential energy, E, stored in a spring as a function of its compression,x, is given by the equation E(x)=1/2kx2...where k is the stiffness of the spring. Using a nested loop, calculate the energy stored in three different springs with stiffness equal to: 100 N/cm, 175 N/cm, and 220 N/cm and store the results in a matrix E, i.e., each row (or column) of E corresponds to a different spring. On the same set of axes plot E vs. x for compression values x=0 cm to x=20 cm in steps of 1 cm. Use different line styles for each spring and add a legend to the plot. 2.
