A diver leaves the platform with her body straight. Her body is in a relatively slow rotation, with an angular speed of 4.0 rad/s. She then tucks into a pike position, with her body essentially folded in half. When straight her moment of inertia is 13.5 kg·m2, and when in the pike position it is 3.4 kg·m2. The next two questions have to do with this diver. Calculate her angular momentum when straight. a. 6 kg·m2/s b. 39 kg·m2/s c....
1. A diver springs upward from a three-meters board. At the instant she contacts the water her speed is 8.90 m/s and her body makes an angle of 75.0° with respect to the surface of the water a) Determine her initial velocity (magnitude and direction). b) How much time did she spend in the air? 1. A diver springs upward from a three-meters board. At the instant she contacts the water her speed is 8.90 m/s and her body makes...
