A solid sphere of mass `m` and radius `R` is rolling without slipping as shown in figure. Find angular momentum of the sphere about z-axis.

Text Solution

Verified by Experts

`L=mvr_(bot)+I_(c)omega`
`=mvR+((2)/(5)mR^(2))((v)/(R))`
`=(7)/(5)mvR`
this is clockwise, or along negative z-axis
`thereforeL=(-(7)/(5)mvR)hatk`
