A 0.2 kg object at rest is subjected to a force $(0.3\widehat{\mathrm{i}}-0.4\widehat{\mathrm{j}})\mathrm{N}$ . What is its velocity vector after 6 sec

• A

  $(9\widehat{\mathrm{i}}-12\widehat{\mathrm{j}})$

• B

  $(8\widehat{\mathrm{i}}-16\widehat{\mathrm{j}})$

• C

  $(12\widehat{\mathrm{i}}-9\widehat{\mathrm{j}})$

• D

  $(16\widehat{\mathrm{i}}-8\widehat{\mathrm{j}})$
