Question 8 10 pts A person stands on a bathroom scale in a motionless elevator. When the elevator begins to move, the scale briefly reads only 0.72 of his/her regular weight. Calculate the acceleration of the elevator and find the direction of acceleration. (Choose upward as the positive direction and express the direction of the acceleration using the sign of the result, which must be in units of mis and include 2 digit after the decimal point. Maximum of 5% of error is accepted in your answer. Take g=9.50 mis 10 pts Question 9 from am a re suspended by a cord from a pulley

Answer 1

let us suppose the by am/s2 so, from elevator es going down Newton's and law of motion mg -N=ma N = mg-mas ① mg - 0.72 g = nia ( Given N=0:72mg) a=0:28g Ta=20744 misal direction downward as the man weight decreases like it if this is clear to you! Thanks!! please
