Heya mate,

Here is your answer,. ⬇️⬇️

_____________

The bus started from rest.

Thus, initial velocity (u) = 0 m/s.

The bus acquired a speed of 15 m/s in 8 seconds.

Thus, time taken (t) = 8 s.

And final velocity (v) = 15 m/s.

Thus, Acceleration

= (15-0)/ 8

= 15/8

= 1.875 m/s.

Hope this helps,.

If helps, please mark 'thanks'
