Just after leaving the platform, the diver’s fully extended 90-kg body has a rotational speed of 0.32 rev/s about an axis normal to the plane of the trajectory. Estimate the angular velocity N later in the dive when the diver has assumed the tuck position. Model the diver as a uniform rod in the first position and as a uniform sphere in the second.

Explanation:

The diver can be modelled by using the Principle of Angular Moment Conservation:

The final angular velocity is:

Let assume that L = 1.60 m and R = 0.15 m.

okay i have so many questions. but the big one here is: um wt..f is this mess? ?

as we probably am aware that our atmosphere or air have various levels, each level has different gasses, and each gas has another porousness. at the point when the light originates from lower porousness to higher penetrability, it alters its course. with the goal that implies that when the light originates from the moon to the earth, it alters it's course a lot more occasions. it essentially implies that the state of the light piece of the moon is changed on the earth.

not copied too! hope this !

h o h o hope you have a merry christmas!
