The leader is the weakest part of a fly-fishing line. A given leader can withstand 19 N of force. A trout when caught will accelerate, taking advantage of slack in the line, and some trout are strong enough to snap the line. Assume that with the line taut and the rod unable to flex further, a 1.3 kg trout is just able to snap this leader. How much time would it take this trout to accelerate from rest to 5.0 m/s if it were free of the line?
