Two spacemen A and B are floating is gravity free space with zero velocity relative to each other. "A" has a mass of 120 kg and "B" has a mass of 90kg which includes a 5 kg radio box. "B" throws the box towards "A" with a velocity of 2m/x and A catches it. The change in velocity of each one is

A

`v_A= 11.8cm//s v_B = 8cm//s `

B

`v_A = 8cm//s v_B = 11.8 cm//s `

C

`v_A = 10cm//s v_B = 10 cm//s `

D

`v_A = 9cm //s v_B = 12cm//s`
