Question

A school bus moves down a road, dropping off students after school. The bus slows down from a speed of 15 meters per second to a full stop over a distance of 55 meters in 11 seconds. What is the average speed, in meters per second, of the school bus while the bus is slowing down? * 3.7 5.0 26 40

Answer 1

The average speed of the school bus as it slows down to a stop is 5.0 meters per second, calculated by dividing the distance of 55 meters by the time of 11 seconds.

Step-by-step explanation:

The question asks for the average speed of a school bus as it slows down to a stop. The bus decelerates over a distance of 55 meters and takes 11 seconds to come to a complete stop from a speed of 15 meters per second. To find the average speed, we can use the formula for average speed, which is the total distance traveled divided by the total time taken.

In this case, the bus covers 55 meters in 11 seconds. Therefore, the average speed is calculated as follows:

Average speed = Total distance / Total time = 55 meters / 11 seconds = 5 meters per second.

The average speed of the school bus while it is slowing down is 5.0 meters per second.

Answer 2

Given :

A school bus moves down a road, dropping off students after school.

The bus slows down from a speed of 15 meters per second to a full stop over a distance of 55 meters in 11 seconds.

To Find :

The average speed, in meters per second, of the school bus while the bus is slowing down.

Solution :

Initial velocity, u = 15 m/s.

Distance travelled, d = 55 m.

Time taken, t = 11 s.

Final velocity, v = 0 m/s.

We know, average velocity is given by :

`v_(avg)=(distance)/(time)\\\\v_(avg)= (55)/(11)\ m/s\\\\v_(avg)=5 \ m/s`

Therefore, average velocity is 5 m/s.

Hence, this is the required solution.
