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 rough for question, if cofficient of friction is 0.2 in both axis)
Co-ordinates of center of mass where it will stop finally are :-

A

(2.0 m,14.25 m)

B

(2.25 m,10 m)

C

(3.75 m,9 m)

D

(1.75 m,12 m)
