Please answer both parts with diagrams and explanations

(5) Mathiyakom et al 2006a investigates impulse generation, muscle activation, and joint control between the backwards timer and backwards somersault in diving. (a) Draw a free body diagram with force vectors that represents the backwards timer and a free body diagram with force vectors that represents the backwards somersault at the total body level (specifically looking at the push interval). Explain what the difference is between these movements using your free body diagrams. (1 pt) . Refer to Figure 1 for the differences between each dive . However, you should only create 1 free body diagram for each movement (2 total), and you should draw your own resultant reaction force to illustrate the differences in objectives (Figure 1 only has vertical and horizontal RF drawn but not resultant) (b) Summarize what the muscle activation differences and similarities were between the two movements (again, specifically looking at the push interval only). (1 pt) . Refer to Figure 8 for muscle activation results . An asterix refers to a significant difference during that interval for that muscle when comparing dives
