what is the sum of three vectors that when placed tip to tail, form a triangle? If the vectors represent forces on an object what does this imply about the object.

The sum of any number of vectors that form a closed figure like a triangle is always ZERO.
In the case of forces, this means the net force on the object is zero, so according to Newton's second law, the object is not accelerating. (This means it is either at rest or moving in a straight line at a constant speed.)

Sum of these vectors would be zero. Placing them tip to tail is a technique of addition. Only if these three forces all act on the particle, the result would be zero.

it should be Zero.
i think it's representing the pathway of a raquetball, bouncing off of 2 walls & coming to rest at the same exact spot from where it was hit. the fact that it came to rest at exactly the same spot from where it started means that it's total travel (also implying velocity) quantitatively results in zero.
what the heck

zero
the object is either at rest or moves with constant velocity
