To calculate the net force from the vectors 3.4 N i + 3.0 N j and 3.4 N i - 3.0 N j, the correct approach involves summing the components separately. The user initially calculated 6.8 N i + 0 N j, which is incorrect because it overlooks the direction of the j component. The discussion highlights the importance of understanding that the problem asks for acceleration, not just net force, indicating the need to divide the net force by mass to find acceleration. Clarification on vector addition and the distinction between net force and acceleration is essential for solving these types of physics problems. Understanding these concepts can help avoid confusion in future calculations.
