Let $\vec{F}$ Be a Vector Field with Constant Magnitude $\| \vec { F } \| = 8$

Short Answer

Let $\vec{F}$ be a vector field with constant magnitude $\| \vec { F } \| = 8$ Suppose that $\vec { r } ( t ) ,$ 0 $\le$ t $\le$ 5, is a parameterization of a flow line C of $\vec{F}$ .
Find $\int _ { C } \vec { F } \cdot d \vec { r }$
