A person is standing on a spring bathroom scale on the floor of an elevator which is moving up and slowing down at the rate of 3
aleksklad [387]

Answer:

F_N=1194.24\ N

Explanation:

Given that,

The elevator is moving up and slowing down at the rate of, a=3\ m/s^2

The acceleration due to gravity, g=9.8\ m/s^2

Mass of the person, m = 93.3 kg

To find,

The reading of the scale.

Solution,

As the elevator is moving down with some acceleration. The net force acting on it is given by :

F_N=ma+mg

F_N=m(a+g)

F_N=93.3(3+9.8)

F_N=1194.24\ N

So, the scale will read 1194.24 N.
