Instead nick hands the rope with the scale to his friend barney, who stands on the ground. barney pulls on the rope so that the spring scale again reads 320 n. what is nick's acceleration now, again using upward as positive.

force is mass*acceleration.

we have a very small mass: 11.4*0.001 kg

if we want 0.035n of force, we need an acceleration:

0.035 = 11.4*0.001*a

a = 0.035/(11.4*0.001) m/s^2

resonant frequency

c because the news are a source of information of things that happen on the daily and shows evidence about that particular topic
