What is the magnitude of the resultant velocity of the seed?

In summary, the resultant velocity of the seed is the overall velocity that takes into account both the magnitude and direction of the individual velocities acting on the seed. The magnitude of the resultant velocity can be calculated using the Pythagorean theorem, where the square of the resultant velocity is equal to the sum of the squares of the individual velocities. The magnitude of the resultant velocity of the seed can be affected by the magnitude and direction of the individual velocities, as well as the angle at which they intersect. In certain cases, the magnitude of the resultant velocity can be greater than the individual velocities when they are acting in opposite directions and are not equal in magnitude. However, air resistance can decrease the magnitude of the resultant velocity by opposing the motion of the seed

Here's the question:

A bird drops a seed, which falls with a steady vertical terminal velocity of 4.8 m/s. A
slight breeze blows the seed toward the west at 1.2 m/s.

(a) What is the magnitude of the resultant velocity of the seed?

(b) What is the direction (in degrees west of the vertical) of the resultant velocity
of the seed?

Velocities are vectors, yes? You can draw a diagram if that helps.
 

1. What is the resultant velocity of the seed?

The resultant velocity of the seed is the overall velocity that takes into account both the magnitude and direction of the individual velocities acting on the seed.

2. How is the magnitude of the resultant velocity of the seed calculated?

The magnitude of the resultant velocity can be calculated using the Pythagorean theorem, where the square of the resultant velocity is equal to the sum of the squares of the individual velocities.

3. What factors affect the magnitude of the resultant velocity of the seed?

The magnitude of the resultant velocity of the seed can be affected by the magnitude and direction of the individual velocities, as well as the angle at which they intersect.

4. Can the magnitude of the resultant velocity of the seed ever be greater than the individual velocities?

Yes, the magnitude of the resultant velocity can be greater than the individual velocities when the individual velocities are acting in opposite directions and are not equal in magnitude.

5. How does air resistance impact the magnitude of the resultant velocity of the seed?

Air resistance can decrease the magnitude of the resultant velocity of the seed, as it acts as a force that opposes the motion of the seed and can slow it down.
