Question

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

Answer 1

Answer:

= 0.0185 m/s²

Explanation:

Given,

➟ 1 minute = 60 seconds

➟ 10 minute = 10(60) = 600 seconds

Multiply by 5/18(To change km/h into m/s)

➟ 40 km/h = 40(5/18)

➟ 200/18 = 11.11 m/s

So here we have

u = 0 m/s

v = 11.11 m/s

t = 600 seconds

Now,

⟹ v = u + at

⟹ 11.11 = 0 + a(600)

⟹ 11.11 = 600a

⟹ 11.11/600 = a

⟹ 0.0185 m/s² = a

Hence, the acceleration of the train is 0.0185 m/s².
