edugen/lti/main.uni Halliday, Fundamentals of Physics, 10e Helo l PRINTER VERSION 4 BACK Chapter 05, Problem 026 The tension at which a fishing line snaps is commonly called the line's "strength." What minimum strength is needed for a line that is to stop a salmon of weight 86 N in 12 cm if the fish is initially drifting horizontally at 2.4 m/s? Assume a constant deceleration.

Explanation / Answer

Mass of salmon = 86/9.8 = 8.78 kg

Deceleration = v²/(2s) = 2.4²/(2×0.12) = 24 m/s²

So tension = ma = 8.78×24 = 210.72 N
