How is a particle's two-dimensional position represented?
A
The motion is instantaneously vertical, not necessarily at rest.
B
tanθ=vyvx\tan\theta=\dfrac{v_y}{v_x}tanθ=vxvy
C
r(t)=(x(t)y(t))\mathbf r(t)=\begin{pmatrix}x(t)\\y(t)\end{pmatrix}r(t)=(x(t)y(t))
D
v(t)=(3t2+25−4t) m s−1\mathbf v(t)=\begin{pmatrix}3t^2+2\\5-4t\end{pmatrix}\text{ m s}^{-1}v(t)=(3t2+25−4t) m s−1
