PART 2: VECTORS 1. Given vectors (3,2,6) and 17(4,1,5) determine the angle between a and 17. (3 marks) 2. Determine the direction angles for vector iv = (3,4,12) (3 marks) 3. If lal =12 , '5' =8, and the angle between them is 60, determine the magnitude and direction of 5+5. Include a diagram. (4 marks) 4. A ship has a cruising speed of 25 km/h and a heading of N10W. There is a current of 6 km/h, travelling N70W. What is the resultant velocity of the ship
