Newton's First law of motion -- Boy jumping vertically on a moving train

[Mikasun1108]

Homework Statement

A boy was inside a train moving at a constant speed when he jumped. When he landed on the floor of the train after the jump, he did not land on the same spot as the train was moving forward.
a. True
b. False

Relevant Equations

Newton's first law of motion

I'm not sure if my answer is correct but I think the answer is false.
Thank you for your help :)

Show some effort : why do you think the statement is "false" ?

I personally think that it is because the train wasn't accelerating therefore it will land at the same spot. And also sort of because of my own experience (not entirely sure) when flight attendence pour some water/juice etc the liquid comes straight down and not on a different angle. Therefore my logic brought me to this conclusion. Sorry fo just adding this now, i wasn't entirely sure.

"When flight attendence pour some water/juice etc the liquid comes straight down and not on a different angle."

That's a good observation. The aircraft is moving almost inertially (i.e. with negligible acceleration), so things inside the aircraft behave according to Newton's laws. And, objects dropped fall straight down.

Thank you for the extra information, really appreciate it :)
