You are an engineer designing a pinball machine. Local customers have expressed that their ideal velocity for the pinball (mass = 0.1kg) to be launched at 12.6m/s. In general, people compress the pinball machine spring by 0.2m to reach this initial velocity for the pinball.

Using the information listed in the description, which type of spring do you choose to most closely reach the targeted launch speed of 12.6 m/s? Show your work and explain your answer using what you know of kinetic energy, elastic potential energy, and conservation of energy.
