Apassenger bus is travelling 28.0 m/s to the right when the driver applies the brakes. the bus stops in 5.00 s. what is the acceleration of the bus as it comes to a stop?

 - 5.60 m/s^2

Explanation:

Speed of passenger bus = 28.0 m/s to the right  

Time took for the bus stops = 5.00 s.

What is the acceleration of the bus as it comes to a stop = x

Step 1:

Calculate the change in velocity  

d = v2 (Final velocity)  - v1 (Initial Velocity)

d= 0 – 28

d= -28m/s  

Acceleration=  Change in velocity / time taken

Acceleration = -28 m/s / 5

Acceleration = - 5.60 m/s^2 to the right

Note: Do not forget the units, otherwise they make cost you marks!

because if the tool that you are using is not balanced it there would be false mass.
