A body of mass 2 kg moving with velocity of v _ in =3 i +4 j ms ⁻¹ enters into a constant force field of 6 N directed along positive z -axis. If the body remains in the field for a period of 5 3 seconds, then velocity of the body when it emerges from force field is

Options

  1. A4 i +3 j +5 k
  2. B3 i +4 j +5 k
  3. C3 i +4 j -5 k
  4. D3 i +4 j + 5 k

Correct answer

B. 3 i +4 j +5 k

Step-by-step solution

aligned & a = B 2 k =3 k , t = 5 3 ~s & u =3 i +4 j & v = u + a t =3 i +4 j +5 k aligned
