Question
A person stands on a bathroom scale in a motionless elevator. When the elevator begins to move, the scale briefly reads only 0.69 of the person's regular weight. Calculate the magnitude of the acceleration of the elevator.

m= 0.69
a=mg-g
a=(0.69)(9.80)-9.80
a=-3.038 m/s^2
Acceleration is 3.038 m/s^2 downward
a=mg-g
a=(0.69)(9.80)-9.80
a=-3.038 m/s^2
Acceleration is 3.038 m/s^2 downward

Fnet = ma
ma = Fn-Fg
Fn = 0.69Fg = 0.69mg
Fg = mg
ma = 0.69mg - mg
cancel out all m in equation and left with:
a=0.69g-g
a=-.31g=-.31*9.8= -3.04 m/s^2
ANSWER: a = -3.04 m/s^2
ma = Fn-Fg
Fn = 0.69Fg = 0.69mg
Fg = mg
ma = 0.69mg - mg

a=-.31g=-.31*9.8= -3.04 m/s^2
ANSWER: a = -3.04 m/s^2
