Vector uses in physics – Calculate velocity and acceleration – Exercise 3866

Exercise

Given a vector radius of a point as a function of time

\vec{r}(t)=\vec{v_0}t-\frac{1}{2}gt^2\vec{k}

Where the initial velocity is

\vec{v_0}=\vec{v}(0)=(v_{01},v_{02},v_{03})

Calculate the velocity function, the acceleration function and their values (size).

Final Answer

\vec{v}(t)=(v_{01},v_{02},v_{03}-gt)

|\vec{v}(t)|=\sqrt{v^2_{01},v^2_{02},{(v_{03}-gt)}^2}

\vec{a}(t)=-g\vec{k}

|\vec{a}(t)|=g
