The frequency of a simple harmonic oscillator such as a spring-mass system is given by

where
k is the spring constant
m is the mass attached to the spring.
Re-arranging the formula, we get:

and since we know the constant of the spring:

and the frequency of oscillation:
f=1.00 Hz
we can find the value of the mass attached to it:
I'm not exactly sure but I'm thinking that it's the last one. Sorry if I'm wrong
this process is called parellelogram method of resolving vectors.
Answer:
Im not sure
Explanation:
I don't take physics cuz im in 9th grade. so. idk but I will find out and come back with an answer.
If a man has a mass of 83 kilograms on Earth, the force of gravity on his body be on the moon 135.6N. force =mass*acc , 83 * 9.8/6= 813.4/6 = 135.6N
