A spaceship with a mass of 1000.0 kg is traveling through deep space with a velocity of (693.03,0) m/s. Two rocket engines fire in sequence (assume the mass of the ejected fuel is negligible). The first rocket provides a thrust of (1200.0t²,0) for 10.0 sec. The second engine provides a thrust of (0, 9859.51sin(31.65t)) for /31.65 secohds. What is the magnitude of the velocity of the spaceship after the second rocket fires. (1618) A) O1093.03 m/s B) O1258.66 m/s C) O1093.21 m/s D) 0468.92 m/s E) O741.29 m/s
