To be able to add and subtract vectors using geometric and vector addition. A brother and sister are playing in the woods, when suddenly the brother realizes that they are separated. The last place he remembers seeing his sister is at a particularly large tree. The brother traveled d_1 = 23.5 mat theta_1 = 25.5 degree from the tree then turned and traveled d_2 = 12.0 m at theta_2 = 137 degree. Meanwhile, the sister traveled d_3 = 18.5 m at an angle of theta_3 = -110 degree from the tree. The angles are given with respect to east with counterclockwise being defined as positive Using the parallelogram law to add these vectors geometrically, determine the displacement of the boy relative to the tree. Express your answers, separated by a comma, to three significant figures. Enter the angle measured counterclockwise from the positive x axis. Displacement from the boy to the girl Using the method of vector addition by components, determine the displacement from the boy to the girl. Express your answers, separated by a comma, to three significant figures. Enter the angle measured counterclockwise from the positive x axis.
