- A space craft studying the faint rings of Jupiter is struck and crashes into one of Jupiter's moons. The ship is badly damaged and it is not clear which moon the craft smashed into. One of the micro-cameras, hanging from part of the wreckage transmits some data before going dark. The camera is found to be swinging from a thin piece of wire thought to be 6.8 cm in length and the footage indicates that it was swinging with an oscillation frequency of 0.751 Hz. NASA scientists realize that they can use this data to identify the moon upon which the craft has landed by estimating the gravitational constant of the moon. a) What is the period of oscillation? b) Estimate the gravitational acceleration, "g" of this moon.x (m) 2 1 t (s) 0.8 0.2 0.4 0.6 11. A particle undergoes SHM represented by the graph. Which of the following is true about the amplitude and period of oscillations? Amplitude Period 0.8 s A) 1 m 0.1 s B) 1 m 0.4 s C) 1 m 0.4 s D) 2 mAlthough California is known for earthquakes, it has large regions dotted with precariously balanced rocks that would be easily toppled by even a mild earthquake. Apparently no major earthquakes have occurred in those regions. If an earthquake were to put such a rock into sinusoidal oscillation (parallel to the ground) with a frequency of 2.2 Hz, an oscillation amplitude of 1.0 cm would cause the rock to topple.What would be the magnitude of the maximum acceleration of the oscillation, in terms of g?
