5. The graph¹ below shows the force exerted on the raptorial appendage as a function of its contraction distance, for both the contraction and release of the appendage. What is the resilience of the raptorial appendage? Use the area under the red dashed line to approximate the area under the "contraction" curve and the area of the green triangle to approximate the area under the "release" curve. 20 15 Contraction 10 Release 5 0.1 0.3 0.4 0.2 Contraction distance (mm) 6. Use the graph and your answer to the previous question to determine the kinetic energy of the raptorial appendage when it is released from rest after being contracted by a distance of 0.3 mm. Assume there is no change in gravitational potential energy during this motion. You may ignore any friction and drag forces that the water exerts on the appendage. Force (N)
