Calculate the apparent weight (normal force) in newtons on person with a mass of m=77 kg standing on a bathroom scale in an elevator that is traveling upwards with a constant velocity of 5.3 m/s.



Answer :

The apparent weight (normal force) on a person with a mass of m=77 kg standing on an elevator bathroom scale while ascending at a constant speed of 5.3 m/s is 754.6N (newtons).

Consider the instantaneous speed to be the speed that the speedometer registers at any given moment in time, and the average speed to be the average of all the measurements taken throughout the journey.

The discomfort we experience when running solid objects can be attributed to the normal force. The normal force is the force applied by surfaces to stop solid objects from passing through other normal force.

m= 77kg

elevator travelling with a constant speed at 5.3m/s, that means acceleration is zero.

Ay=0

Fn = mg (since Ay=o)

Fn=(77*9.8)

Fn=754.6N
