A diver (m = 60 kg) jumps from a diving board. At takeoff, his angular momentum about the transverse axis is 30 kg⋅m2/s. His radius of gyration about the transverse axis is 0.5 m at this instant. During the dive, he tucks and reduces his radius of gyrations about the transverse axis to 0.2 m.
After he tucks the body, what is his angular velocity about the transverse axis?
A.) 12.5 rad/s
B.) 1 rad/s
C.) 2.5 rad/s
D.) 10 rad/s

P is an 85 kg diver who leaps off the diving board with an angular momentum of 24 kg·m2/s and curls into a ball to rotate (position A). Their radius of gyration when in the ball is 0.3m. P then fully extends into a headfirst diving position (position B) where their radius of gyration is 1.6m. The time from position A to position B occurs in 0.8 seconds. (You do not need to convert radians to meters) a. What is...
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.

(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 jumps from a diving board and rotates in the air. Is their translational momentum conserved? Is their angular momentum conserved? Why or why not? i dont understand the question and teacher said it's asking while they rotate in the air
Determine the angular acceleration of the 24-kg diving board the instant the man jumps off. Assume that the board is uniform and rigid, and that at the instant he jumps off the spring is compressed a maximum amount of 250 mm,w-0, and the board is horizontal. Take k 6.4kN/m (Figure 1) Express your answer to three significant figures and include the appropriate units. alue Units re 1 of 1 Submit Request Answer Part B 15m15m Determine the horizontal component of...

8. Joe is spinning on a stool at 24 rad/s about his longitudinal axis when he abducts his arms and increases his radius of gyration from 10 cm to 45 cm. Is his angular momentum is conserved, what is his angular velocity (in rad/s) about the longitudinal axis after he increases his radius of gyration?
1. What is the angular momentum of a 0.240-kg ball rotating on the end of a thin string in a circle of radius 1.35 m at an angular speed of 15.0 rad/s ? 2. A diver can reduce her moment of inertia by a factor of about 4.0 when changing from the straight position to the tuck position. 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...
