Problem 8-61 Cons. of Momentum - Part 6 - B
A space vehicle and its fuel tank are moving with a velocity of \(350\; m/s\) toward a space station. The fuel tank is then jettisoned to the rear so that its velocity is only \(250\; m/s\) toward the station. What is the new speed of the space vehicle? The mass of the vehicle is \(3.25\) times that of the tank. [Ans. \(380\; m/s\)]
Accumulated Solution
| Solution | Before | After |
|---|---|---|
| (B) | \((m_1 + m_2)v\) | \(m_1\; v_{1}{'} + m_2\; v_{2}{ }'\) |
Correct!
There are no external forces in the system consisting of \(m_1\) and \(m_2\).
(A) True
(B) False
