Question 1122127
.
<pre>
The resulting force magnitude is


|F| = {{{sqrt(50^2 + 60^2 - 2*cos(180^o-37^o)*50*60)}}} = {{{sqrt(50^2 + 60^2 - 2cos(143^o)*50*60)}}} grams.


Use your calculator.


To understand why it is so, use the parallelogram rule of adding forces (vectors) and make a sketch.

<U>Notice</U>.  It was VERY long time ago when the force was measured in kilograms and grams.


In modern unit system the basic unit of force is Newton.
