## amistre64 2 years ago Im sure I got (a), but I have no idea what it is asking for in (b). (a) Find the single force that is equivalent to the 2 forces shown. (b) What is the value of a third force to make the net force zero.

$(a)=80sin(75^o)+60\sqrt{3}=181.2~N$

the picture in the book is 2 guys pulling on a mule that wont budge; and b is asking for something to do with, what force does a third person have to exert on the mule to make a net for equal to zero

Need help or not ?

i need help understanding what the question is asking for, yes

$-80cos(75^o)+120cos(60^o)=39.3N$ so maybe its asking to find a third value that will balance that part of it out
