Question
As the captain of the scientific team sent to Planet
Physics, one of your tasks is to measure g. You have
a long, thin wire labeled 1.01 g/m and a 1.26 kg
weight. You have your accurate space cadet
chronometer but, unfortunately, you seem to have
forgotten a meter stick. Undeterred, you first find the
midpoint of the wire by folding it in half. You then
attach one end of the wire to the wall of your
laboratory, stretch it horizontally to pass over a pulley
at the midpoint of the wire, then tie the 1.26 kg weight
to the end hanging over the pulley. By vibrating the
wire, and measuring time with your chronometer, you
find that the wire's second harmonic frequency is
200 Hz. Next, with the 1.26 kg weight still tied to one
end of the wire, you attach the other end to the ceiling
to make a pendulum. You find that the pendulum
requires 319 s to complete 200 oscillations. Pulling
out your trusty calculator, you get to work.
Part A
What value of g will you report back to headquarters?
