he will not jerk the line because it will break , so he will reel it gradually and smoothly so it will hold. why? can somebody explain according to newton’s laws of motion.
Basically, inertia. A body at rest wants to stay a rest, a moving body wants to stay moving. With gentle pressure on the line (within it’s breaking strain) the shark will start to move, as it moves it will take less effort to keep it moving. If it was jerked from a standstill, the inertia is such that the load could exceed the breaking strain of the line.
When the shark comes to the surface, it would need to be lifted out as the water will no longer offer boyancy and the weight of sharky will break the line.
