Determine the magnitude of the force F1F1 component acting along the uu axis. Express your answer to three significant figures and include the appropriate units. View Available Hint(s) Hint 1. How to approach the problemopened hint Since the uu and vv axes are not perpendicular, the force component magnitudes cannot be determined just using one proper trigonometric function. So we need to establish a triangle, a part of a parallelogram corresponding to the parallelogram law. Force F1F1 and its components will be the sides of that triangle. Then, finding the angles of the triangle and using the sine law should help to determine the force component magnitudes.

The first image below shows force F1 and the axes.

3.62 kN

Explanation: The second figure below express the parallelogram method to calculate the u component of force F1.

The Parallelogram Method is a method to determine resultant force and is applied as described in the question above.

With the three components, and and angles, it can be used the Law of Sines, which states:

i.e., there is a relation of proportionality between an angle and its opposite side.

For the triangle below:

u = 3.62

The magnitude of the component acting along the u-axis is 3.62kN.

the design of a ski jumping suit involves a trade-off between giving the skiers lift to get higher jumps and ensuring the skier does not face a lot of drag before the jump itself. an expansive suit may to lift the skier higher, but at the same time, it will also increase the air resistance. higher air resistance as the skier goes down the slope limits the speed of the jump. a big suit also increases the risk of losing balance or control, especially if there's a strong gust of wind. while technologically enhanced suits a lot, clothing is not the only factor in a ski jumper’s success. gathering speed while skiing down the slope, ensuring good speed on the ramp, and maintaining good body posture and form in the air all contribute to a ski jumper's success.
