A bus is traveling with a uniform acceleration of 2.75 meters/second2. If the initial velocity of the bus is 16.5 meters/second, what will its velocity be after 9.00 seconds?

Respuesta :

v=u+at

v = 16.5 +  (2.75)*(9)                                              where v is  the final speed
                                                                                u is the initial speed
                                                                               a is the acceleration 
                                                                                  t is the time
v=41.25 m/s 

Answer:

Final speed, v = 41.25 m/s

Explanation:

It is given that,

Acceleration of the bus, [tex]a=2.75\ m/s^2[/tex]

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 :

[tex]a=\dfrac{v-u}{t}[/tex]

[tex]v=u+at[/tex]

[tex]v=16.5+2.75\times 9[/tex]

v = 41.25 m/s

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