Questions and Problems (1) Use head-to-tail graphical vector addition to find $\vec{R}$ and then $\vec{E}$ in Procedure 1. Show your graph below, using a scale of 0.4 N = 1 cm. Use a ruler and a protractor to carefully construct the vectors $\vec{F_1}$ and $\vec{F_2}$ from their measured values, and apply direct measurement on your graph rather than trig or geometry to find $\vec{E}$. Finally, compare your theoretical prediction for $\vec{R}$ from this graph to the measured values obtained previously in Procedure 1 Procedure 1 Graph Scale 0.4 N = 1 cm $\vec{E}$ Theoretical Experimental % Difference Prediction Measurement Mass .2817kg .2816kg .39% Force Magnitude 2.77N 2.76N .36% Angle 286.6° 286.5° .035%
