If the average velocity of a body moving with uniform acceleration under the action of a force is “v” and the impulse it receives during a displacement of “s” is “I”, the constant force acting on the body is given by

• A

  $\frac{\mathrm{I}\times \mathrm{v}}{2\mathrm{s}}$

• B

  $\frac{2\mathrm{I}\times \mathrm{v}}{\mathrm{s}}$

• C

  $\frac{\mathrm{I}\times \mathrm{v}}{\mathrm{s}}$

• D

  $\frac{\mathrm{I}\times \mathrm{s}}{\mathrm{v}}$
