Question

A train starting from a railway station and moving with uniform accelaration attains a speed 40km/h in 10 minutes.Find its acceleration​

Answer 1

Answer:

acceleration =delta v/ delta t

a=v/t

a=40/10

a=4m/s^2

Answer 2

Answer:

Step-by-step explanation:

u=0km/h
v=40km/h
changing 40km/h to m/s
40*5/18  = 11.1m/s
t= 10 mins
changing time to seconds
t=10*60= 600 secs

NOW

v=u+at
11.1=0+600*a
11.1=600a
600a=11.1
a=11.1/600
a=111/6000

a=0.0185m/s square
