2019 F = ma Exam B — Question 4

Consider two identical masses that interact only by gravitational attraction to each other. If one mass is fixed in place and the other is released from rest, then the two masses collide in time T. If both masses are released from rest, they collide in time — Source: Question 4, 2019 F = ma Exam B, © 2019 American Association of Physics Teachers (AAPT) and the U.S. Physics Team.
