If an oscillation of a mass on a spring has 17 times the energy of another oscillation of the same mass on the same spring, what is the ratio of the amplitudes of the two oscillations? Give the ratio (larger amplitude)/(smaller amplitude). NOTE! You must enter your answer as a decimal number, not as a fraction. For instance, if the answer is 1/3, you must enter 0.333.
