Comprehension # 5 One particle of mass `1 kg` is moving along positive x-axis with velocity `3 m//s`. Another particle of mass `2 kg` is moving along y-axis with `6 m//s`. At time `t = 0, 1 kg` mass is at `(3m, 0)` and `2 kg` at `(0, 9m), x - y` plane is the horizontal plane. (Surface is smooth for question 1 and rough for question 2 and 3) The centre of mass of the two particles is moving in a straight line for which equation is :
A
y = x+ 2
B
y = 4x+ 2
C
y = 2x-4
D
y = 2x+4
