A 12-kg mass package is in a non-atmosphere asteroid of mass 1.7 x 1014 kg and radius 2,000 m. The package is released with a powerful spring whose stiffness is 315 N / m. After being launched, the package is observed to have a speed of 3.0 m / s when it is at a distance of 5,000 m from the center of the asteroid. Calculate how much the spring was compressed to launch the package?
)A group of Vestas V-100-1.8 wind turbines can be seen
on the drive between Pullman and Spokane (near Rosalia). One is
shown in the photo; the length of a blade is ~50m. This windmill
stops working at wind speeds greater than 22 mph (9.84 m/s).
Assuming this maximum wind speed, an air density of 1.2 kg/m³, and
that half of the air approaching the circular area spanned by the
spinning blades is redirected perpendicularly, calculate the reaction
force at the top of the tower.
