Question 31

A particle $P\,$ moves with a constant velocity $ms−1(3\mathbf{i} + 2\mathbf{j}) \text{ ms}^{-1}$ with respect to a fixed origin $O$ . It passes through the point $A\,$ whose position vector is $m(2\mathbf{i} + 11\mathbf{j}) \text{ m}$ at $t = 0$ .

a.

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

[2]

b.

Calculate the distance of $P\,$ from $O\,$ when $t = 2$ .
