Question

A bus increase its speed from 20km/h in 10 seconds What is the acceleration of bus?​

Answer 1

Answer:

Dear Student

Given, Initial Velocity = 20km/s

Final Velocity = 50km/s

Time = 10sec = 10/3600 = 1/360 hr

Acceleration = Change in velocity/ time

= 30 x 360)/1 = 10800 Km/hr

Answer 2

Answer:

It's acceleration is 0.83m/s²

Explanation:

1km/h=5m/18s

=20km/h in m/s=20×5/18

=50/9

=5.5m/s

=50km/h in m/s=50×5/18

=125/9

=13.8m/s

Final Velocity=13.8m/s

Initial Velocity=5.5m/s

=a=v-u/t

a=13.8-5.5/10

a=8.3/10

a=83/100

a=0.83m/s²
