A computer is protected against impact by foam packaging (spring stiffness, k = 100 N/cm; mass, m = 11 kg, including packaging). The maximum acceleration that the computer can withstand on impact with a hard surface is 4g. At the maximum acceptable impact acceleration, how much does the packaging compress upon impact? Give the answer in cm. What is the maximum height, h, in cm that the case can fall from without damaging the computer?
