QuestionA solid sphere of radius 18.0 cm and mass 10.0 kg starts from rest and rolls without slipping a distance of $\mathrm{L}=7.0 \mathrm{~m}$ down a house roof that is inclined at $30^{\circ}$.
What is the angular speed about its center as it leaves the house roof? $38.9 \frac{\mathrm{rad}}{\mathrm{s}}$
The height of the outside wall of the house is $h=9 \mathrm{~m}$. What is the horizontal displacement of the sphere between the time it which it leaves the roof and the time at which it hits the ground? 15.2 m
