When a diver goes from a layout position to a somersault position, what changes are made to the moment of inertia and angular velocity?
Homework Answers
From the law of conservation of angular momentum.
I×w= constant which means that is moment of inertia increases than angular velocity will decreases and vice versa.
So from layout position to somersault position moment of inertia decreases and from conservation law angular velocity increases.

When a diver gets into a tuck position by pulling in her arms and legs, she increases her angular speed. Before she goes into the tuck position, her angular velocity is 5.5 rad/s, and she has a moment of inertia of 1.8 kg · m2. Once she gets into the tuck position, her angular speed is 17.1 rad/s. Determine her moment of inertia, in kg · m2, when she is in the tuck position. Assume the net torque on her...

A 50 kg diver in a full layout position, with a total body radius of gyration with respect to her transverse prinicpal axis equal to 0.45 m, leaves a springboard with an angular velocity of 6 rad/s. What is the diver's angular velocity when she assumes a tuck position, reducing her radius of gyration to 0.25 m?

A diver (such as the one shown in the figure(Figure 1) ) can reduce her moment of inertia by a factor of about 3.5 when changing from the straight position to the tuck position. A) If she makes 2.0 rotations in 1.5 s when in the tuck position, what is her angular speed (rev/s) when in the straight position?

Estimate the ratio of angular velocities for the rotation of a diver between the full tuck position and the full layout position. (Assume that, in layout position, the diver is a thin rod of length 2.5 m and that, in full tuck position, the diver is a sphere of radius 0.50 m.) ωtuck ωlayout = Because the net external torque acting on the diver is zero, the diver's angular momentum will remain constant as she rotates from the full tuck...

a 60 kg gymnast leaves the ground with angular momentum about his transverse axis of 15 kg m2/s. His radius of gyration about the transverse axis is 0.7 m at take-off. During his subsequent somersault, he reduces his radius of gyration to 0.4 m. (a) What is the moment of inertia of the gymnast at take-off? During the somersault? (b) What is the angular velocity of the gymnast at take-off? During the somersault? (c) If it takes the gymnast 0.25...

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....
