Question

A bus increases its speed from 20 km/h to 60 km/h in 5 sec. Find the acceleration
the bus.​

Answer 1

Answer:

Hope it gonna help you.

Explanation:

v1 = 20km/hr= 20×5/18=50/9 m./sec

v2 = 60km/hr= 60×5/18=50/3 m/sec

Acceleration = final velocity - initial velocity / the time taken between initial and final velocity

so Acceleration= (v2-v1)/5

=(50/3-50/9)/5

=100/9×5

=20/9 m/sec^2

1 m/sec^2= 12960 km/hr^2

20/9m/sec^2=12960×20/9 km/hr^2

= 28800 km/hr^2
