Question 15

A particle $P\,$ moves in a straight line with constant velocity. Initially $P\,$ is at the point $A\,$ with position vector $m(4\mathbf{i} - 3\mathbf{j}) \text{ m}$ . At time $t = 3$ , $P\,$ is at the point $B\,$ with position vector $m(-5\mathbf{i} + 9\mathbf{j}) \text{ m}$ .

a.

Find the velocity of $P$ .

b.

When $t = 5$ $P\,$ is at the point $C$ . Find the distance $A C$ .
