Question

The bus starts from rest and attains 40 km per hour velocity after 10 seconds calculate the acceleration of the bus in kilometre per hour into hours and metre per second into hour

Answer 1

Answer:

Explanation:

u=0,v=40,t=10,a=?

v=u+at

40*5/18=10a

a=20/18 m/s^2

Answer 2

Answer:

Initial velocity =0km/h=0m/s (u)

Final velocity=40km/h=11.1m/s (v)

Time taken =10s

Acceleration=(v-u) /t

=(11.1-0)10

=1.11m/s^2

In km=

40-0/10/3600

40/1/360

40*360

14400km/h
