The weight of the meterstick is:
and this weight is applied at the center of mass of the meterstick, so at x=0.50 m, therefore at a distance
from the pivot.
The torque generated by the weight of the meterstick around the pivot is:
To keep the system in equilibrium, the mass of 0.50 kg must generate an equal torque with opposite direction of rotation, so it must be located at a distance d2 somewhere between x=0 and x=0.40 m. The magnitude of the torque should be the same, 0.20 Nm, and so we have:
from which we find the value of d2:
So, the mass should be put at x=-0.04 m from the pivot, therefore at the x=36 cm mark.

So, the initial altitude of the parachuter is approximately <u>(C). 123 m</u>.
<h2>Introduction</h2>Hi ! In this question, I will help you. In this question, you will learn about the fall time of the free fall motion. Free fall is a downward vertical motion without being preceded by an initial velocity. When moving in free fall, the following equations apply:
<h3>The equation for calculating the height (h)</h3>With the following condition :
- t = interval of the time (s)
- h = height or any other displacement at vertical line (m)
- g = acceleration of the gravity (m/s²)
- v = velocity (m/s)
We know that :
- t = interval of the time = 5 s
- g = acceleration of the gravity = 9.81 m/s²
What was asked :
- h = height or displacement at vertical line = ... m
Step by Step :
So, the initial altitude of the parachuter is approximately 123 m (C.)
