hi please help me asap! :)

What is the sum of the vectors 14 m [20 E of N] and 10 m [225]? A. 6.5 m, [69 degrees N of W] B. 13.1 m, [20 degrees 8 of W] C. 17 m [280 degrees] D. 7.1 m [45 degrees W of S] A feature at the Olympic Games is the "dive camera\" that tapes a diver's progress from the platform to under the water. The camera falls at the same free fall rate as the diver (assume initial velocity of the camera is zero). If a dive platform is 10.0 m high how many complete dives can be recorded on a 30.0 minute tape, if the camera les from the start of each dive until 1.00 s of underwater time for each dive and if there is a 1.00 s interval of blank tape between each dive? (Le. a complete dive consists of the dive, the underwater recording and one second blank space) A. 100 B. 250 C. 524 D. 704
