Unformatted text preview: 6. Draw vector representing the vector sum A+B Data Table(s): Angle A = 130 o Angle B = 160 o Angle C = 70 o 5N, 3N, 2N See Graph Paper Observations: When weight’s position is changed, the angles and spring scale values were different. Calculations: sqrt(2N 2 +3N 2 )=3.6N = resultant Reasons for Not perfect angle or length measurements Error: Summary 1. What was the length of the resultant? Questions: Conclusion: 1. 3.6N...
