The force required to compress a non-standard spring as a function of displacement is given by the equationF(x) = -Asin(bx) + kx,where A = 25 N, b = 11 rad/m, and k = 68 N/m. Enter a general equation in terms of the given variables for the work required to compress this spring from position x1 to x2.  Calculate the work done in joules as the spring is compressed from x = 0 to x1 = 21 cm.  Calculate the work done in joules as the spring is compressed from x1 = 21 cm to x2 = 66 cm
