Oliver has a mass of 76.2 kg. He is riding in an elevator that has a downward acceleration of 1.37 m/s^2.
With what magnitude force does the elevator floor push upward on Oliver?

F = W + f = mg + ma = m(g + a) = 76.2(9.81 + 1.37)
F (in Newtons) is the apparent weight due to gravity (g) and the acceleration (a) operating downward on the body (m).
You can do the math. (I presumed the elevator was rising. Reverse the (a) sign, if by "downward" you meant the elevator is moving downward.)

Oliver is obese and needs to lose weight!! Nobody really cares about people when they get that fat, he's taking up more then his fair share of space and I think we should just let the elevator crash on his fat #ss!
