WOMAN IN ELEVATOR
A woman weighs Fg= 650 N when standing on a stationary scale. Now, the woman is riding an elevator from the 1st floor to the 10th floor. As the elevator approaches the 10th floor, it decreases its upward speed from 8 m/s to 1 m/s in a time interval of 1 s. What is the average force exerted by the elevator floor on this woman during this 1 s interval? Use g=10 m/s2.
this are the options, but i would like to have the equation
292.50 N
97.50 N
146.25 N
195.00 N
390.00 N
