Question

8) A bus decreases its velocity from 80
km/h to 60 km/h is 5 seconds. Find the
acceleration of the bus.​

Answer 1

Given:-

Initial velocity(u)=80km/h

=>80×5/18

=>200/9 m/s

Final velocity(v)=60km/h

=>60×5/18

=>150/9 m/s

Time(t)=5s

To find:-

Acceleration of the bus(a)

Solution:-

We know that------

$a = \frac{v - u}{t}$

=>a=(150/9-200/9)/5

=>a= -50/9/5

=>a= -10/9 m/s²

Thus,accleration of the bus is -10/9m/s² or -1.11m/s²
