Homework Statement
Particles of mass m, 2m, and 3m are arranged as shown in (Figure 1) , far from any other objects. These three particles interact only gravitationally, so that each particle experiences a vector sum of forces due to the other two.
Is the analysis of the motion of this system straightforward?
Is the analysis of the motion of this system straightforward?
a. No. If released from rest, the system will rotate clockwise around the common center of mass. The accelerations are not constant, so the motion is difficult to describe completely.
b. No. If released from rest, each particle moves in a straight line toward the common center of mass. The accelerations are not constant, so the motion is difficult to describe completely.
c. Yes. If released from rest, the system will rotate clockwise around the common center of mass. The accelerations are constant, so the motion is easy to describe completely.
d. Yes. If released from rest, each particle moves in a straight line toward the common center of mass. The accelerations are constant, so the motion is easy to describe completely.
