An elevator accelerates upward at 1.2 m/s^2. The acceleration of gravity is 9.8 m/s^2
What is the upward force exerted by the
floor of the elevator on a(n) 53 kg passenger?
Answer in units of N.

And the question tied to it is

If the same elevator accelerates downwards
with an acceleration of 1.2 m/s^2. what is the
upward force exerted by the elevator floor on
the passenger?
Answer in units of N.

hello there!

your answer is a “generator”

a generator does not create energy but instead it transforms it.

it’s basically a motor working in reverse.

force is based upon mass and acceleration.the statement is not always true.

it can be explained from newton's second law of motion.

as per newton's second law of motion the rate of change of momentum is directly proportional to the applied force and takes place along the direction of force.

mathematically it can be written as -

                                              ⇒      

here   k is the proportionality constant whose value is 1.

                                                            [a is the acceleration=dv/dt]

hence we see that force not only depends on mass and acceleration but also on velocity and rate of change of mass. force f will depend on mass and acceleration only when mass is constant.

hence the statement that force is based upon mass and acceleration is false.
