Question

a bus motion increases its speed from 30 kilometre per hour to 60 kilometre per hour in 20 seconds find its acceleration​

Answer 1

Answer:

If the motion is along a straight line then Speed=velocity.

then acceleration = Final Velocity -initial velocity / Total time.

Then

60-30/20

30/20

3/2= 1.5Km/s

now convert the unit of /s in /hr.

i hope it will help you.

You can even conbert the time in hrs and then solve the sum

Answer 2

SOLUTION :

GIVEN:

initial velocity = u = 30 km/hr

final velocity = v = 60 km/hr

time taken = t = 20 sec

acceleration = ?

as final and initial velocity is in km/hr , we have to convert it into m/s ,

Now ,

we know ,

a = (v -u )/t
