Vector uses in physics – Calculate motion – Exercise 3874

Exercise

Particle acceleration depends on time according to the acceleration formula

$\vec{a}(t)=18\cos(3t)\vec{i}-18\sin(3t)\vec{j}$

The initial vector radius of the particle is

$\vec{r}(0)=(2,0,1)$

And the initial velocity of the particle is

$\vec{v}(0)=(0,2,4)$

Calculate the equation of motion of the particle.
