The acceleration of the person standing on the elevator is 8.15 m/s².
How to calculate the acceleration of the person?
The acceleration of the person is calculated by applying Newton's second law of motion as follows;
F(net) = ma
where;
- F(net) is the net force on the person
- m is the mass of the person
- a is the acceleration of the person
The reading of the elevator is equal to the net force on the person;
The given parameters include;
F(net) = 439 N
mass, m = 53.9 kg
a = F(net) / m
a = (439 N ) / 53.9 kg
a = 8.15 m/s²
