To determine the average velocity vector, we need to find the displacement vector between the initial and final positions of the particle.Given:Initial position: (0, 2.9) mFinal position: (2.9, 0) mTime interval: 1.0 sThe displacement vector is given by:
mThe average velocity vector is given by:
m/sTherefore, the average velocity vector is:
m/s
