HOMEWORK 1: VECTORS NT2B-CCT4: ADDING Two VECTORS-MAGNITUDE OF THE RESULTANT Three students are discussing the magnitude of the resultant of the addition of the vectors A and B. Vector A has a magnitude of 5 centimeters, and vector B has a magnitude of 3 centimetens. Alexis "We'd have to Anow the directions of the vectors to koow how big the resultantis soing to be. Bert Since we are only asked about the magnitade, we don't have to worry about the directions The magnitude is just the size, so to find the magnitade of the resultant we just have to add the sizes of the vectors. The magnihiude of the resultant in this case is 8 centimeters this case the magnitude is the square root of 34, a little less than 6 centimeters The resulant is the vector that you hove to add to the first vwector to get the second vector. In Cara No, these are vectors, and to find the magnitude you have to use the Pythagorean theorem. In Dacia: this case the resultant is 2 Which, if any, of these students do you agree with? AlevisBertCaraDacia Nons of them Please explain your reasoning

Explanation / Answer

Only Alexis is correct as the addition of vectors depends not only on their magnitude but also on the direction of the vectors.
