An object moving due west collides with a second object that is initially at rest. Just after the collision the first object is moving toward the southeast. Just after the collision the second object must be moving toward the

Northwest.

Explanation:

After the collision the second object which was at rest would change its direction and move towards the Northwest. The object in motion was coming from the east and traveling towards the west, where it deflects against a stationery object which changes its direction to southeast. And the object which was at rest moves toward the northwest.
