Chapter 4, Problem 84GP
A fisherman in a boat is using a “10-lb test” fishing line. This means that the line can exert a force of 45 Ν without breaking (1 lb = 4.45 Ν). (a) How heavy a fish can the fisherman land if he pulls the fish up vertically at constant speed? (b) If he accelerates the fish upward at 2.0 m/s2 what maximum weight fish can he land? (c) Is it possible to land a 15-lb trout, on 10-lb test line? Why or why not?

A fisherman has caught a very large, 5.0 kg fish from a dock that is 2.0 m above the water. He is using a lightweight fishing line that will break under a tension of 60N or more. He is eager to get the fish to the dock in the shortest possible time.
If the fish is at rest at the water's surface, what's the least amount of time in which the fisherman can raise the fish to the dock without losing it?
Express your answer with the appropriate units.
From a standstill, a 77.0 kg basketball player bends their knees and pushes against the floor andextends legs vertically 30.0 cm before jumping vertically off the ground and reaches a maximumheight of 25.0 inches above the ground. Assume the force the floor exerts on the player is constant.What is the force the floor exerts on the player? Give answer in lbs. (Let 4.45 N = 1 lb., 1 inch = 2.54 cm)
