Question
A lazy fish sees your fishing hook. The fish is initially located at position (3 m,-2 m) and
drifts towards the fishing hook that is located at position (6 m, 0 m). The fish is a real lunker and
has a mass of m = 9.1 kg.
a) What is the displacement vector for the fish during this
time interval? Express your answer using unit-vector
notation (i.e. ->Ar = _î + __j)
(6 m, 0 m)
|(3 m, -2 m)
Suppose the river exerted a constant force of F* = (28 N)î – (14 N)ĵ on the fish as it moved
toward the hook.
b) How much work was done on the fish by the river?
