Question

The diver leaves the platform with an initial upward speed of 2.8 m/s. A stationary camera on the ground is programmed to track the diver throughout the dive by rotating the lens to keep the diver centered in the captured image. State the values of $\dot{\theta}$ and $\ddot{\theta}$ at the instant the diver enters the water. Treat the diver as a particle which has only vertical motion. 2.8 m/s 6.0 m Answers: At the instant the diver enters the water, $\dot{\theta}$ = rad/s $\ddot{\theta}$ = rad/s$^2$ 10 m

Step 1

The camera is at the origin O(0,0). The diver's motion is purely vertical. Let y be the vertical position of the diver relative to the camera. Let x be the horizontal position of the diver relative to the camera. From the diagram, the horizontal distance from the Show more…
