1) A computer to be used in a satellite must be able to withstand accelerations up to 25 times the acceleration due to gravity. In a test to see whether it meets this specification, the computer is bolted to a frame that is vibrated back and forth in simple harmonic motion at a frequency of 9.5 Hz. What is the minimum amplitude of vibration that must be used in this test?
2) A pendulum clock can be approximated as a simple pendulum of length 1.00 m and keeps accurate time at a location where g is 9.83 m/s2. In a location where g is 9.78 m/s2, what must be the new length of the pendulum, such that the clock continues to keep accurate time (that is, its period remains the same)?
