Answer:
The force exerted by the ocean tide is directed to the right (east).
The force exerted by the wind is directed to the northwest (45° N of W).
We should separate the x- and y- components of the wind force, and evaluate each component separately.
We denote the direction to the right as the positive direction, so the x-component of the wind force is in the negative direction.
The resultant force is as follows:
The resultant acceleration can be found by Newton's Second Law:
The magnitude of the resultant acceleration is
Answer:
Explanation:
It is given that,
Dimension of the rectangular roof, (6.17 m × 5.92 m)
The maximum net outward force,
The density of air,
The Bernoulli equation is used to find wind speed of this roof blow outward. It is given by :
Here, (since air inside the roof is not moving)
Since,
So, the wind speed of this roof blow outward is 29.13 m/s. Hence, this is the required solution.
