Platform Water Figure 1 Figure 2 Figure 3 The figures above show three stages of a dive performed by an athlete. During the dive, the athlete completes several rotations in midair while traveling from the platform to the surface of the water. Figure 1 shows the athlete just after jumping off the platform. Figure 2 shows the athlete rotating in midair. Figure 3 shows the athlete about to enter the water. (a) In a clear, coherent paragraph-length response that may also contain figures and/or equations, explain why the athlete's angular speed increases between Figure 1 and Figure 2 but decreases between Figure 2 and Figure 3. (b) Is the rotational kinetic energy K2,rot of the athlete in Figure 2 greater than, less than, or equal to the rotational kinetic energy K1,rot of the athlete in Figure 1 ? K2,rot > K1,rot K2,rot K1,rot Briefly explain your answer. K2,rot = K1,rot Platform Water Figure 1 Figure 2 Figure 3 The figures above show three stages of a dive performed by an athlete.
