Textbook QuestionCALC A hollow, thin-walled sphere of mass 12.0 kg and diameter 48.0 cm is rotating about an axle through its center. The angle (in radians) through which it turns as a function of time (in seconds) is given by θ(t) = At^2 + Bt^4, where A has numerical value 1.50 and B has numerical value 1.10. (a) What are the units of the constants A and B?1129viewsHas a video solution.
Textbook QuestionA woman with mass 50 kg is standing on the rim of a large disk that is rotating at 0.80 rev/s about an axis through its center. The disk has mass 110 kg and radius 4.0 m. Calculate the magnitude of the total angular momentum of the woman–disk system. (Assume that you can treat the woman as a point.)1691viewsHas a video solution.

Textbook QuestionThe position of a particle with mass m traveling on a helical path (see Fig. 11–48) is given byr→ = R cos (2πz/d) î + R sin (2πz/d) ĵ + zk̂where R and d are the radius and pitch of the helix, respectively, and z has time dependence z = v𝓏 t where v𝓏 is the (constant) component of velocity in the z direction. Determine the time-dependent angular momentum L→ of the particle about the origin.<IMAGE>62viewsHas a video solution.
