8. Here are the motion graphs showing 129 0 the person moving forward for 4.0 s, starting at -9.0 m, traveling to 11.0 m. 6.0 Find values and write the units for the following (2 SF): [4 marks, T/1; 0.5 Position (sx/m) 0.0 marks per blank below] -6.0 a. initial position ( X; ): -9.0 b. final position ( X ): -12.0 10.0 c. total displacement ( 's ): 5.0 (shade the area relating this on the v-t graph) Velocity (vx/ms-1) 0.0 (show the calculation of that area ) -5.0 -10.0 8.1 d. time interval ( t ): e. initial velocity ( 'u ): 4.0 f. final velocity ( "v ): Acceleration (a/ms-2) 0.0 g. acceleration ( 'a ): -4.0 (draw the rise over the run on the v-t graph) (show a calculation of that slope) -8.1 0 2 Time (t/s)
