Answer:
20.996 m
Step-by-step explanation:
Given:
Initial velocity,

Final velocity,

Total time taken,
s.
∴ Acceleration is given as,
m/s²
Now, using Newton's equation of motion, we find the displacement.
Displacement is given as:

Plug in 0 for
, 4.91257 for
and 1.74 for
. Solve for
.
This gives,

Therefore, the train's displacement in the first 4.91257 s of motion is 20.996 m.
