All right, I am doing my physics homework and I just cannot figure this one out. I have been trying for literally over an hour, so I am running out of ideas. Here it is.
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 76 N in 13 cm if the fish is initially drifting at 3.1 m/s? Assume a constant deceleration.
All right, so clearly this has to do with force, which is going to end up being the mass of the fish times its decleration. But because they are asking for strength, I am guessing it a magnitude and not a vector. So, I have tried things such as using the velocity over the meters taken to stop the fish, to get time and then apply that to get the acceleration, but that was clearly wrong as the time changes due to the deceleration. I have done all kinds of things, I need help to figure this one out. Thank you
