• 1. Astronaut Astronaut X Figure 1 Astronaut Y Astronaut X Figure 2 35. Two astronauts are connected by a taut cable and are initially at rest with respect to a nearby space station. Astronaut X throws a large container to Astronaut Y. Figure 1 above shows the astronauts immediately after the container is thrown by Astronaut X, and Figure 2 shows the astronauts immediately after the container is caught by Astronaut Y. Which of the following describes the motion of Astronaut Y in Figures 1 and 2? Figure l Figure 2 (A) Does not move (B) Moves to the left (C) Does not move (D) Moves to the left Moves to the right Moves to the right Does not move Does not move Solution 1. When Astronaut X throws the container the container moves towards right, due to conversation of momentum, the astronaut X will move to the left , since Y is also connected to X, he will start moving towards left. 2. Since Y is already in motion towards left, if he catches the container, due to conservation of momentum, he will start moving to the right. Hence B.
