A 100kg person rides in an elevator accelerating 2m/s2 upward. 1.) what is the magnitude (in N) of the gravitational force on the person? 2.) what is the magnitude of the normal force of the floor on the person’s feet? 3.) what value would the acceleration have to be for the magnitude of the normal force exerted by the floor on the person’s feet to be equal to the magnitude of their weight?

An elevator starts from rest at the bottom of a building and is now moving steadily upward (no longer speeding up). Which statement is correct about its motion now and why? A) The net force on the elevator is zero B) The net force on the elevator is greater than zero C) The net force on the elevator is negative, downward D) The net force is equal to the weight of the elevator

You step into a high-speed elevator on the top floor of a tall building and push the button for the first floor. The elevator accelerates downwards. How does the normal force N exerted on you by the floor of the elevator compare to your weight? Select one: O a. the normal force is equal to your weight O b. It depends on how fast you are moving O c. the normal force is greater than your weight O d. the...

Assume that while ascending, an elevator has the same magnitude of acceleration "a" during starting (accelerating) and stopping (decelerating). A person stands on a scale in that elevator, and hence pushes downwards on the scale. The scale also reacts with an upward normal force. The maximum and minimum scale readings are Nace = 600 N and N dec = 400 N, respectively. acceleration of...

2) Rita is in an elevator that is moving at a constant velocity downward. If the elevator now experiences an acceleration so that it speeds up, the normal force Rita experiences A) becomes greater than her weight. B) remains equal to her weight. C) becomes less than her weight, but not equal to zero. D) becomes zero. E) cannot be determined without more information. 11) A rope connects object A (mass 4m) with object B (mass m). (Object A is...
