AP Physics question helppppp!!

[From: ] [author: ] [Date: 11-09-28] [Hit: ]
Though your normal weight is 650 N, the scale at the moment reads 750 N.(a) Is the acceleration of the elevator upward, downward, or zero?(b) Calculate the magnitude of the elevators acceleration.......
As part of a physics experiment, you stand on a bathroom scale in an elevator. Though your normal weight is 650 N, the scale at the moment reads 750 N.

(a) Is the acceleration of the elevator upward, downward, or zero?
I got: upward

(b) Calculate the magnitude of the elevator's acceleration.
m/s2
I got:1.509
(c) What, if anything, can you say about the velocity of the elevator?
1. Elevator has positive acceleration upward
2. Elevator has positive acceleration downward
3. Velocity remains constant

I only need the answer to number 3....Thanks!!

A strange question since (c) is the same as (a).

Anyway you are correct.

a positive in the upward direction
b g/6.5 = 9.8/6.5 = 1.51
c 1 as already answered in (a)

-
The elevator has positive acceleration upward, answer 1
