Acceleration due to gravity measured with wire and ball

To measure the acceleration due to gravity on a distant planet, an astronaut hangs a 0.070 kg ball from the end of a wire. The wire has a length of 1.5 m and a linear density of 3.1 10-4 kg/m. Using electronic equipment, the astronaut measures the time for a transverse pulse to travel the length of the wire and obtains a value of 0.085 s. The mass of the wire is negligible compared to the mass of the ball. Determine the acceleration due to gravity.

Solution Summary

This solution shows how to find the acceleration due to gravity with a transverse pulse through a wire.
