Question

The physics teacher walks 4 meters East, 2 meters South, 4 meters West, and finally 2 meters North. The entire motion lasted for 24 seconds. Determine the average speed and the average velocity.​

Answer 1

вот надеюсь что правильно

Answer 2

To determine the average speed and average velocity, we first need to find the total distance traveled and the total displacement.

Given:

• Distance East = 4 meters
• Distance South = 2 meters
• Distance West = 4 meters
• Distance North = 2 meters
• Time = 24 seconds

Total distance = Distance East + Distance South + Distance West + Distance North Total distance = 4 + 2 + 4 + 2 = 12 meters

Total displacement = Final position - Initial position

Final position = (4 meters East - 4 meters West, 2 meters South - 2 meters North) Final position = (0 meters, 0 meters)

Initial position = (0 meters, 0 meters)

Total displacement = (0 meters, 0 meters) - (0 meters, 0 meters) Total displacement = (0 meters, 0 meters)

Now we can calculate the average speed and average velocity.

Average speed = Total distance / Time Average speed = 12 meters / 24 seconds Average speed = 0.5 meters/second

Average velocity = Total displacement / Time Average velocity = (0 meters, 0 meters) / 24 seconds Average velocity = (0 meters/second, 0 meters/second)

So, the average speed is 0.5 meters/second and the average velocity is 0 meters/second (since the displacement is zero).
