A pogo stick has a spring with a spring constant of 2.5×104N/m,2.5 \times 10^{4} \text{N}/\text{m}, which can be compressed 12.0 cm. To what maximum height from the uncompressed spring can a child jump on the stick using only the energy in the spring, if the child and stick have a total mass of 40 kg?
