A rocket moving vertically -- Find the cosmonaut's weight

[inv4lid]

Homework Statement

A rocket during launch from the Earth's surface moves vertically with an acceleration of 22m / s ^ 2. Find the cosmonaut's weight inside the cabin if his mass is 90kg.

Homework Equations

The problem belongs to "Elasticity. Moving under the action of elastic force" chapter.
General gravity relating to man = 900N;
N - G = ma?
N = m(a+g)
N = 90*(22+10) = 2880 N

The Attempt at a Solution

No idea currently, trying to solve[/B]

What the definition of weight?

What do you mean ”no idea”? You essentially solved it.

Just got it, ty anyway

There's solving a problem and knowing you've solved it!

I think the two are the same (as long as you got it right). Hence the addition of the ”essentially” - the remaining step being to realize that what was computed was the sought quantity.
