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>

Answer:
Faith, to me is almost like hope but for faith you need to believe. Some people associate the word faith with religion. But that's not it. Faith is really just a stronger term than believing someone. Like you can believe in someone but not have faith in that same person. You can have faith in someone but to do that you have to believe and trust them.
