Answer:
Its rotation will be 3.89x10⁴ rad/s.
Explanation:
We can find the rotation speed by conservation of the angular momentum:

(1)
The initial angular speed is:

The moment of inertia (I) of a sphere is:
(2)
Where m is 9 times the sun's mass and r is the sun's radius
By entering equation (2) into (1) we have:

Hence, its rotation will be 3.89x10⁴ rad/s.

<span>The de-acceleration or negative acceleration of stopping is what damages bones. The ground is rigid and therefore the change in momentum when striking the ground will be large. On the trampoline, the elasticity of the material means that the momentum changes more slowly, resulting in smaller accelerations.</span>
