A body is projected up along an inclined plane from the bottom with speed $v_1$. If it reaches the bottom of the plane with a velocity $v_2$, find $\frac{v_1}{v_2}$if θ is the angle of inclination with the horizontal and µ be the coefficient of friction.

• A

  $\frac{\sin \theta +\mu \cos \theta }{\sin \theta -\mu \cos \theta }$
• B

  $\sqrt{\frac{\sin \theta +\mu \cos \theta }{\sin \theta -\mu \cos \theta }}$
• C

  $\frac{\cos \theta +\mu \sin \theta }{\cos \theta -\mu \sin \theta }$
• D

  $\sqrt{\frac{\cos \theta +\mu \sin \theta }{\cos \theta -\mu \sin \theta }}$
