- 5Calculate the increase in velocity (in m/s) of a 4810 kg space probe that expels 3210 kg of its mass at an exhaust velocity of 4.00 ✕ 103 m/s. You may assume the gravitational force is negligible at the probe's location. The answer is 4400 m/s given by the homework website I tried using the conservation of momentum and the conservation of kinetic energy but did not get the right answer.If a 12 kg mass, moving at 8 m/s to the right, hits and sticks to a 8 kg mass, moving at 11 m/s to the right, and they travel off together at the same speed to the right, find that speed. Hint: both masses are moving to the right, so both velocities are positive. Use the "hit and stick" or inelastic formula

If its engine has an exhaust speed of 2.45 ✕ 103 m/s, determine the required ratio Mi Mf of its initial mass to its final mass. (The difference Mi − Mf equals the mass of the ejected fuel.)Two asteroids with the same mass are in the connecting line between Mars andJupiter.
