Question 13

A toy boat $P\,$ moves across a pond with constant velocity. Initially $P\,$ is at the point $A\,$ with position vector $m(-2\mathbf{i} + 7\mathbf{j}) \text{ m}$ . At time $t = 2$ seconds, $P\,$ is at the point $B\,$ with position vector $m(8\mathbf{i} - 17\mathbf{j}) \text{ m}$ .

a.

Find the velocity of $P$ .

b.

When $t = 3$ $P\,$ is at the point $C$ . Find the distance $A C$ .
