Newton's Laws/Forces Question.

  1. Sep 21, 2008 #1
    1. The problem statement, all variables and given/known data

    Two horizontal forces act on a 11 kg mass. One force has a magnitude of 8 N and is directed due north. The second force toward the east has a magnitude of 6 N. What is the magnitude of the acceleration of the mass?


    2. Relevant equations

    F=ma

    a=F(net)/mass


    3. The attempt at a solution

    Force North = 8
    Force East = 6

    8-6=2, net force =2

    a=2/11

    a=.1818


    I think that might be wrong, because I feel like there should be vectors or something involved?

    I think there should be vectors involved. Find the magnitude of a vector 8N going N and 6N going east--Pythagorean Theorem. Then when you found the resultant of those two forces, take this force and divide it by the mass (11kg); thereby, giving you the acceleration.

    I know this might be a random question. But where did you get this question??
