on the ground a man A is movingwith velocity [3icap -4jcap]m/s and anotherman B is moving with velocity [icap+jcap]m/s relative to A. Find the relative velocity of B with respect to the ground.
Add the ground velocity vector of A to the relative velocity of B with respect to A.
3i - 4j + (i + j) = 4i - 3j m/s
