Two particles A and B, with masses mA and mB, respectively, are a distance r0apart. Particle B is fixed in space, and A is initially at rest. Using Eq. (1.6) on p. 5 and assuming that the diameters of the masses are negligible, determine the time it takes for the two particles to come into contact if mA = 1 kg, mB = 2 kg, and r0 = 1 m. Assume that the two masses are infinitely far from any other mass.
