A rocket, which is in deep space and initially at rest relative to an inertial reference frame, has a mass of 50.5 × 105 kg, of which 9.42 × 105 kg is fuel. The rocket engine is then fired for 200 s, during which fuel is consumed at the rate of 410 kg/s. The speed of the exhaust products relative to the rocket is 4.46 km/s. (a) What is the rocket's thrust? After the 200 s firing, what are (b) the mass and (c) the speed of the rocket?

(8%) Problem 11: A student launches a small rocket which starts from rest at ground level. At a height of h- 1.85 km the rocket reaches a speed of ve 395 m/s. At that height the rocket runs out of fuel, so there is no longer any thrust propelling it. Take the positive direction to be upward in this problem.
