Answer 2

1.The net accelerating force :--

here,

Force exerted by engine = 40,000 N

Force of Friction = 5000 N

Now net accelerating force = [40,000 - 5000]

= 35,000Newton

2. Acceleration of Train:---

Here,

Mass of 1 wagon. = 2000kg

Mass of 5 wagon = [ 2000 x 5 ]

= 10,000 kg

now,

Force = Mass x acceleration.

35000 = 10,000 x a

Acceleration = 35000 \ 10000

= 3.5 ms^2 ( answer)
