Ans
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 seccnds. What is the magnitude of the velocity of the spaceship after the second rocket fires.
