Two astronauts, A and B, both with mass of 60 kg, are moving along a straight line in the same direction in a "weightless" spaceship. Relative to the spaceship the speed of A is 2 m/s and that of B is 1 m/s. A is carrying a bag of mass 5 kg with him. To avoid collision with B, A throws the bag with a speed v relative to the spaceship towards B and B catches it. Find the minimum value of v.
(1) 7.8 m/s
(2) 26.0 m/s
(3) 14.0 m/s
(4) 9.2 m/s
