Answer:
Final speed, v = 41.25 m/s
Step-by-step explanation:
It is given that,
Acceleration of the bus,

Initial velocity of the bus, u = 16.5 m/s
We have to find the velocity (v) of the bus after 9 seconds.
The rate of change of velocity is called as the acceleration of the bus. Mathematically, it can be written as :



v = 41.25 m/s
So, the final speed of the bus after 9 seconds is 41.25 m/s
