The initial velocity vector v; points North and has magnitude of 5.6 m/s Five second later, the final velocity vector vf points East, and has the same magnitude as the initial velocity vector. (a) The direction of the change in velocity vector Av=v - vis: OA. West OB. East OC. North-West OD. South-East O E. South-West OF. North-East b) The magnitude of the change in velocity vector Av=v-vis: m/s (0.2 m/s)
