Question

A destroyer sights a ship traveling with constant velocity 5j, whose position vector at the time of sighting is 2000(3i+j) relative to the the destroyer, distances being in meters (m) and velocity in m/s. The destroyer immediately begins to move with velocity k(4i + 3J), where k is a constant, in order to intercept the ship. find k and the time to intercept. Find also the distance between the vessels when half the time to interception has elapsed.
