A fisherman is fishing from a bridge and is using a "33N testline." In other words, the line will sustain a maximum force of33.0 N without breaking. What is the weight of the heaviest fish that can be pulled up vertically, when the line is reeled in (a) at constant speed and (b)with an acceleration whose magnitude is 1.41 m/s2?
Using Newton's law of attraction between two bodies, derive a formula for the gravity field as a function of distance x from the point over the center of mass of a spherical body at depth, d and of density, ρ.?
