The force that the downward moving elevator floor would exert on the person would have to be 500n or greater to withhold the force of the person on the elevator. Please let me know if this helped in any way.

Answer:

Step-by-step 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


F_(net) = ma

so here force on the person is given as


F_n - mg = ma

here we have


a = 0


F_n = mg

as we know that


mg = 500 N


F_n = 500 N

so the floor will exert 500 N force on man
