Answer:
13.9 m/s
Explanation:
The velocity of the train along the inclined surface is given by the ratio between the distance travelled, d, and the time taken, t:
where we have
d = 400 m
t = 5 s
Substituting,
This is the velocity of the train along the inclined plane. Now we can find the vertical component of the velocity by using the formula:
where 
is the angle of the slope. Substituting, we find
