At t= 0, a submarine is moving at v = -8.0 ĵ m/s and is located at r₀ = 5000 î + 125 ĵ + 750 k̂  ( in meters) with respect to a reference island. At t= 0 s, the submarine accelerates at a rate of a = 1.25  î - 2.50  ĵ (m/s²) for 2 minutes. Calculate the submarine's position vector after 2 minutes of motion.
