If the spring of a Jack-in-the-Box is compressed a distance of 8 cm from its relaxed length and then released what is the speed of the toy head when the spring returns to its natural length? Assume the mass of the toy head is 50 g the spring constant is 80 N/m, The toy head news only in the vertical direction. Also disregard the mass of the spring. (Hint: remember that there are two forms of potential energy in the problem.)
