4.1.2 Kinematics (A-level only)

The unit vector [...]\text{[...]}[...] points horizontally in the positive xxx-direction, while j\mathbf{j}j points vertically in the positive yyy-direction.

A

The unit vector i\boxed{\mathbf{i}}i​ points horizontally in the positive xxx-direction, while j\mathbf{j}j points vertically in the positive yyy-direction.

B

The vertical velocity is zero: vy=0v_y=0vy​=0.

C

r=(x0+uxt)i+(y0+uyt−12gt2)j\mathbf{r}=(x_0+u_xt)\mathbf{i}+\left(y_0+u_yt-\frac12gt^2\right)\mathbf{j}r=(x0​+ux​t)i+(y0​+uy​t−21​gt2)j.

D

Its equation is quadratic in xxx with a negative x2x^2x2 coefficient.
