A body is projected up along an inclined plane from the bottom with speed is 2v. If it reaches the bottom of the plane with a velocity v, if $\mathrm{\theta }$ is the angle of inclination with the horizontal and $\mathrm{\mu }$ be the coefficient of friction.

• A

  $\frac{5}{3}\tan \mathrm{\theta }$

• B

  $\frac{3}{5}\tan \mathrm{\theta }$

• C

  $\frac{1}{5}\tan \mathrm{\theta }$

• D

  $\frac{2}{5}\tan \mathrm{\theta }$
