A500n person stands in an elevator that is moving downward at a constant speed. the force that the floor exerts on the person must be

Explanation:

Acceleration of the person is same as the acceleration of the elevator

So here when elevator is moving at uniform velocity so we can say that acceleration of the elevator will be zero

so net force on the person must be zero as per Newton's 2nd law

so here force on the person is given as

here we have

as we know that

so the floor will exert 500 N force on man

the answer is to check all of them! they all apply well at least i think so!
