I think the answer would be C. G<span>ravitational force is proportional to the square of the distance between the centers of both bodies. </span>
Answer:
Explanation:
The work of force 2 will be given by the vectorial equation . We know the value of and have information about its movement, which relates to the net force .
About this movement we can obtain the acceleration using the equation . Since it departs from rest we have .
And then using Newton's 2dn Law we can obtain the net force F=ma, thus we will have
And we had the work done by force 2 as:
(The sign will be given algebraically since we take positive the direction to the right.)
With our values:
<em>Another (shorter but maybe less intuitive way for someone who is learning) way of doing this would have been to say that the work done by both forces would be equal to the variation of kinetic energy:</em>
<em></em>
<em>Which leads us to the previous equation straightforwardly.</em>

The third angle of the triangle should be 37π/72 rad.
We need to know about the triangle rule to solve this problem. One of the rules of the triangle is the total angle inside the triangle is 180⁰.
A + B + C = 180⁰
From the question above, the given parameter is
A = π/9 rad
B = 3π/8 rad
Convert the angle to radian
180⁰ = π
Hence, the total angle should be
A + B + C = π
π/9 + 3π/8 + C = π
C = π - (π/9 + 3π/8)
C = π - 35π/72
C = 37π/72 rad
Hence, the third angle of the triangle should be 37π/72 rad
