15. A person is standing on a weighing machine placed onunumöfmvelocitythe floor of an elevator. The elevator starts going upwith some acceleration, moves with uniform velocity fora while and finally decelerates to stop. The maximunmand the minimum weights recorded are 72 kg and 60 kg.Assuming that the magnitudes of the acceleration andthe deceleration are the same, find (a) the true weightof the person and (b) the magnitude of the acceleration.Take g = 9.9 m/sg/10
