A shuttlecraft is initially moving at 96.0 m/s as it travels in
deep space. The mass of the shuttle given its current fuel level is
approximately 6.41 ✕ 106 kg. When the
shuttle fires its rockets to move faster, the speed of the exhaust
leaving the rockets is 2900 m/s. What is the mass of the fuel
necessary to get the shuttlecraft up to a final speed of 130 m/s?

(a) Imagine that a space probe could be fired as a projectile from the Earth's surface with an initial speed of 4.98 104 m/s relative to the Sun. What would its speed be when it is very far from the Earth (in m/s)? Ignore atmospheric friction, the effects of other planets, and the rotation of the Earth. (Consider the mass of the Sun in your calculations.) (b) What If? The speed provided in part (a) is very difficult to achieve...

5. Rocket guidance A space probe with mass 5180 kg is traveling beyond Saturn with a velocity of 115 m/s. When it is time to alter its course by 30.0°, the probe's thruster jets are fired briefly in a direction perpendicular to its original motion. If the thruster gases are expelled at a speed of 1750 m/s, how much mass must be expelled during the course correction?
