A tree is subject to three forces as follows: 25 N pushing west, 10 N pushing
south (due to the slope it is growing on) and a third force of unknown magnitude and
direction (due to being tied to a stake to prevent it falling). What must the magnitude
and direction of the third force be in order that the tree experiences no net
acceleration?

The magnitude:
"F=\\sqrt{25^2+10^2}=27\\ N"
Direction:
"\\theta=\\arctan{\\frac{10}{25}}=22\\degree\\text{ S of W}"
Numbers and figures are an essential part of our world, necessary for almost everything we do every day. As important…
