Velocity of a particle of mass 2 kg varies with time 't' according to the equation $\overrightarrow{\mathrm{v}}=(2\mathrm{t}\hat{\mathrm{i}}-4\hat{\mathrm{j}})\mathrm{m}/\mathrm{s}$ m/s. Here 'r' is in seconds. The impulse imparted to the particle in the time interval 0 ≤ t ≤ 2s is:

• A

  $\left(4\hat{\mathrm{i}}\right)\mathrm{kg}-\mathrm{m}/\mathrm{s}$

• B

  $(8\hat{\mathrm{i}}-4\hat{\mathrm{j}})\mathrm{kg}-\mathrm{m}/\mathrm{s}$

• C

  $(8\hat{\mathrm{i}}+4\hat{\mathrm{j}})\mathrm{kg}-\mathrm{m}/\mathrm{s}$

• D

  $\left(8\hat{\mathrm{i}}\right)\mathrm{kg}-\mathrm{m}/\mathrm{s}$
