A Mobile Moves With Uniform Reciprocal Movement Knowing That It Travels 90km In 3h. Found Its Speed At The S.I System
Introduction
In the realm of physics, understanding the concept of speed and its relationship with distance and time is crucial. The S.I system, or International System of Units, is a widely accepted system of measurement that provides a standardized way of expressing physical quantities. In this article, we will delve into the concept of uniform reciprocal movement and use it to find the speed of a mobile that travels 90km in 3 hours.
Understanding Uniform Reciprocal Movement
Uniform reciprocal movement refers to a situation where an object moves at a constant speed in a direction that is constantly changing. This type of movement is often seen in circular motion, where an object moves in a circular path at a constant speed. However, in this case, we are dealing with a mobile that travels in a straight line.
Calculating Speed in the S.I System
To calculate the speed of the mobile, we need to use the formula:
Speed = Distance / Time
In the S.I system, the unit of speed is meters per second (m/s). To convert the distance from kilometers to meters, we multiply it by 1000, since there are 1000 meters in a kilometer.
Distance = 90 km x 1000 m/km = 90,000 m
Time = 3 hours x 3600 s/h = 10,800 s
Now, we can plug in the values into the formula:
Speed = 90,000 m / 10,800 s = 8.33 m/s
Converting Speed to Other Units
While the S.I system is widely accepted, there are other units of speed that are commonly used. To convert the speed from meters per second to other units, we can use the following conversion factors:
- 1 m/s = 3.6 km/h
- 1 m/s = 2.23694 mph
Using these conversion factors, we can convert the speed from meters per second to kilometers per hour and miles per hour:
Speed (km/h) = 8.33 m/s x 3.6 km/h/m/s = 30 km/h Speed (mph) = 8.33 m/s x 2.23694 mph/m/s = 18.6 mph
Conclusion
In conclusion, we have used the concept of uniform reciprocal movement to find the speed of a mobile that travels 90km in 3 hours. By using the formula Speed = Distance / Time, we were able to calculate the speed in the S.I system and convert it to other units such as kilometers per hour and miles per hour. This demonstrates the importance of understanding the concept of speed and its relationship with distance and time.
