Question 16

A particle $Q\,$ moves with a constant velocity $ms−1(\mathbf{i} + 4\mathbf{j}) \text{ ms}^{-1}$ with respect to a fixed origin $O$ . It passes through the point $B\,$ whose position vector is $m(2\mathbf{i}) \text{ m}$ at $t = 0$ .

a.

Find the angle in degrees that the velocity vector of $Q\,$ makes with the vector $i\mathbf{i}$ .

[2]

b.

Calculate the distance of $Q\,$ from $O\,$ when $t = 3$ .
