Transcribed Image Text:5.
A uniform solid sphere of radius R = 0.207 m and mass M =
1.82 kg starts from a height vertical H on an inclined plane and rolls DOWN
the incline without slipping. The initial translational speed of the center of mass
of the sphere is V₁ = 1.20 m/s. Assume H = 10.0 m, about 33 feet. Use rotational
inertial for a solid sphere. Show all work.
If you do not consider the rotational part of the kinetic energy, you will get a
zero on this problem.
