Question

1. You are standing inside an elevator that is accelerating upward at 1.5 m/s2. The normal force exerted from the floor on your feet (check all that apply)           

                            
           is in magnitude lower than your weight.                             
           is in magnitude the same as your weight.                             
           is in magnitude larger than your weight.                             
           is directed upward.                             
           is directed downward.                             
           vanishes.


2. You are standing on a scale inside an elevator. The scale reads 145 percent of your weight. What is the acceleration of the elevator?
(Define positive y upward.)    


3. You are standing on a scale inside an elevator. The scale reads 11 percent less than your weight. What is the acceleration of the elevator?
(Define positive y upward.)            

4. You are standing on a scale inside an elevator. The scale reads 50 percent of your weight. What is the acceleration of the elevator?
(Define positive y upward.)

Explanation / Answer

1)    
is in magnitude larger than your weight.
   
   
is directed upward.

2)a = 45*9.8/100 = 4.41m/s^2

3)a = 11*9.8/100 = -1.078 m/s^2

4)a = 50*9.8/100 = -4.9 m/s^2
