1. The problem statement, all variables and given/known data
Stopping a Salmon 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 85 N in 11.6 cm if the fish is initially drifting at 3.0 m/s? Assume a constant acceleration.
2. Relevant equations
X1= -0
X2= .116
V1 = 3.0
V2= 0
A = unknown
T = unknown
T =
3. The attempt at a solution
Solved for A and found it to be -38.7931
m = 85 / 9.8
F = ma
F= (8.673)(-38.793)
F = - 336.45
Not sure what i did wrong
