Not sure how to do this one. Would appreciate a full solution, thanks!

**Problem Statement:**

**Given:**  
This planar water jet (60°F) is deflected by a fixed vane. The velocity of the water jet is 40 ft/s as it enters the vane. The vane changes the direction of the jet, with the incoming angle at 30° and the exiting angle at 60°. The thickness of the jet at the entering and exiting points are 0.1 ft and 0.2 ft, respectively.  

Note: Neglect the effects of gravity.

**Diagram Explanation:**  
- A horizontal line represents the initial path of the water jet with an arrow indicating the velocity of 40 ft/s.  
- The vane is a sloped surface deflecting the water upwards.  
- The angles of 30° and 60° show the change in direction of the water as it enters and exits the vane.  
- The distances of 0.1 ft and 0.2 ft are labeled along the thickness of the jet at these points.

**Question:**  
Find the x and y components of force per unit width needed to hold the vane stationary.
