Unformatted text preview: What will the scale read when the elevator (a) is stationary (b) is ascending with an acceleration of 2.5 ms-2 . (c) is descending with an acceleration of 2.5 ms-2 . (d) is ascending with a uniform velocity of 10 ms-1 . (e) is descending at a constant rate of 10 ms-1 . (f) falls freely after the cables have snapped. 6. m 2 m 1 T 2 T 2 20 kg 10 kg F T 1 A 10-kg block is connected to a 20-kg block by a string. A force applied to the 20-kg block as shown in the figure gives the system an acceleration of 2 ms-2 .
