a) the sum vector is 0

b) the sum vector is greater thatn 30

c) the sum vector is equal to 30

d) the sum vector is less than 30

c) would be the correct answer right? I did v=sqrt(v_x^2 +v_y^2) and got 29.9993 which is quite close to 30.

**bobpursley**, Wednesday, September 19, 2007 at 3:06pmDo the math in polar:

a@0 + a@120 + a@240

Well, the y components of all three of those add to zero.

Now, the x components is a+ -2a*cos60

which is...
