Question 51041: A strong spring is mounted to a steel I-beam so that the spring hangs vertically. A weight is hung from the spring. The energy P (arbitrary units) stored in the spring is given by P(x) = 2x^2, where x is the distance in inches that the end of the spring is stretched from its equilibrium position. Find P(4).
a. 4 units
b. 16 units
c. 8 units
d. 32 units
