1. The problem statement, all variables and given/known data one day you take your bathroom scale with you into an elevator. the scale reads 150 lbs as the door closes. the reading varies between 120 lbs and 170 lbs as the elevator travels up. what is the acceleration of the elevator while its accelerating and decelerating? 2. Relevant equations dynamics equations 3. The attempt at a solution from the first part we know that the scale is telling us the normal force.Fg=Fn Fn=150lbs for the accelerating phase F= Fn-Fg, ma=170lbs - mg this is where i get stuck. where should i go from here?
