Relative Motion Homework: Snow Falling Angle at 6.9 m/s, 79 km/h

In summary, the snowflakes appear to be falling at an angle from the vertical as viewed by the driver of a car traveling at 79 km/h on a straight, level road. The snow is falling at a constant speed of 6.9 m/s, while the car is moving horizontally at 21.94 m/s, indicating that there is an angle present in the snowfall.

Start with how many m/s the car is going.

Ok so that is 21.94 m/s right? I don't know what to do with this info! I am so lost!

The snow is falling vertically at 6.9m/s.

As you look out the window it is also moving horizontally at 21.94m/s

Let's see. Vertically ... horizontally ... hmmm. Think there might be an angle in there somewhere?
 

1. What is the formula for calculating relative motion?

The formula for calculating relative motion is: velocity of object A - velocity of object B = relative velocity.

2. How is the snow falling angle at 6.9 m/s and 79 km/h calculated?

The snow falling angle at 6.9 m/s and 79 km/h is calculated using the formula: angle = arctan (vertical velocity/horizontal velocity).

3. Why is relative motion important in scientific research?

Relative motion is important in scientific research because it allows us to understand the movement and interactions of objects in relation to each other, rather than just their individual movements. This can help us understand complex systems and phenomena.

4. How does the speed of an object affect its relative motion?

The speed of an object affects its relative motion because it determines the magnitude of its velocity and therefore its relative velocity with other objects. Higher speeds can result in larger relative velocities and more noticeable effects of relative motion.

5. Can relative motion be applied to non-physical systems?

Yes, relative motion can be applied to non-physical systems such as economic or social systems. In these cases, the concept of relative motion can help us understand the relationships and interactions between different elements in the system.
