In part a of Fig , a surfer rides on the front side of a wave , at a point where a tangent to the wave has a slope of `theta = 30.0^(@)` . The combined mass of surfer and surfboard is m = 83.0 kg , and the board has a submerged volume of `V = 2.50 xx 10^(-2) m^(3)` . The surfer maintains his position on the wave as the wave moves at constant speed toward shore . What is the magnitude and direction (relative to the positive direction of the x-axis in part b of Fig) of the drag force on the surfboard from the water ?

Explanation

To solve the problem, we will follow these steps:

### Step 1: Understanding the Forces Acting on the Surfboard
The forces acting on the surfboard include:
- The buoyant force (upward)
- The weight of the surfer and surfboard (downward)
- The drag force (acting in the direction opposite to the motion of the wave)
