A wrecking ball with a mass of 81.0 kg hangs from a uniform, heavy-duty chain of mass 21.50 kg. la) Find the maximum magnitude of the tension in the chain. lb} What is the tension at a point one-fourth of the way up from the bottom ofthe chain? Sketch a free-body diagram of your system. Possible answers for maximum tension: (a) 210.70 N [c] 1004.50 N {b} 793.80 N (d) 1741.50 N Possible answers for the tension at a point one-fourth of the way up: (a) 210.20 N (c) 346.43 N lb} 251.13 N to) worse N - Rel who weighs 613 N is standing on a bathroom scale in an elevator that is supported by a cable. As the elevator starts moving, the scale reads 485 N. la) Find the magnitude of the acceleration of the elevator. lb) What is the acceleration ifthe scale reads 713 N? Sketch a free-body diagram of your system. Clue: The magnitude of thenannalforte the scale exerts an the student is the scale reading. Possible answers for the magnitude of the acceleration: (a) - 0.21 m/s' [c] 0.21 was1 {b} - 2.05 m/s' (:1) 2.05 m/s' Possible answers for the magnitude of the acceleration if the scale reads 718 N: (a) - 0.17 m/s' {cl 0.1? mlsI lb} - 1.53 mfs' (d! 1.68 m/s' Kaye is dragging a 134:; sack from the farmer's market to her house. The [ctional force applied by the ground on the sack is 8.25 N and the applied force by Kaye is 24 N. Determine the magnitude of the normal force and the net force acting on the sack of potatoes.
