A particle of mass `1.0g` moving with velocity `v_1=3.0i-2.0j` experiences a perfectly inelastic collision with another particle of mass `2.0g` and velocity `v_2=4.0j-6.0k`. Find the velocity of the formed particle (both the vector v and its modulus), if the components of the vectors `v_1` and `v_2` are given in the SI units.
