Asurfer "hangs ten", and accelerates down the sloping face of a wave. if the surfer’s acceleration is 3.50 m/s2 and friction can be ignored, what is the angle at which the face of the wave is inclined above the horizontal?

Explanation:

Given that,

Acceleration of the surfer,

To find,

The angle.

Solution,

Let is the angle at which the face of the wave is inclined above the horizontal. By considering the free body diagram of the inclined plane,

Therefore, the angle at which the face of the wave is inclined above the horizontal is 20.92 degrees.

probably not if net force is zero
