41. (a) The mass of the elevator is m = (27800/9.80) = 2837 kg and (with + y upward) the acceleration is a = +1.22 m/s 2 . Newton’s second law leads to Tm gm a ga −= ¡ =+ bg which yields T = 3.13 × 10 4 N for the tension. (b) The term “deceleration” means the acceleration vector is in the direction opposite to
