3.2.12 Vectors to solve kinematics problems (A-level only)

What movement does 3i−4j3\mathbf{i}-4\mathbf{j}3i−4j represent?

A

16i+6j m16\mathbf{i}+6\mathbf{j}\text{ m}16i+6j m

B

3 units right and 4 units down.

C

217 m s−12\sqrt{17}\text{ m s}^{-1}217​ m s−1

D

Magnitude: for p=xi+yj\mathbf{p}=x\mathbf{i}+y\mathbf{j}p=xi+yj, ∣p∣=x2+y2\boxed{|\mathbf{p}|=\sqrt{x^2+y^2}}∣p∣=x2+y2​​.
