Question

a bus decreases its speed from 60 km per hour to 40 km per hour in 5 second find the acceleration of the bus​

Answer 1

Answer:

We have to find the Intial and final velocity with time taken

Explanation:

By using the formula of acceleration we can solve the problem

Answer 2

Answer:

60km/h = 60×5/18 m/s = 50/3 m/s ( initial velocity)

40km/h = 40×5/18 m/s = 100/9 m/s (final velocity)

time given = 5seconds

since, acceleration = v-u/t

100/9 - 50/3× 1/5 m/s^2

100-150/9 × 1/5 m/s^2

-50/45 m/s^2

1.11 m/s^2
