An object has velocity \( \vec{v}_{1} \) w.r.t. ground. An observer moving with constant velocity \( \vec{v}_{0} \) w.r.t. ground measures the velocity of the object as \( \vec{v}_{2} \). The magnitudes of three velocities are related by
(1) \( v_{0} \geq v_{1}+v_{2} \)
(2) \( v_{1} \leq v_{2}+v_{0} \)
(3) \( v_{2} \geq v_{1}+v_{0} \)
(4) All of the above
