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

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 :

Therefore, average velocity is 5 m/s.

Hence, this is the required solution.
