प्रश्न

For a particle performing uniform circular motion `vecv=vecomegaxxvecr`obtain an expression for linear acceleration of the particle performing non-uniform circular motion.

Advertisements

उत्तर

`vecv=vecomegaxxvecr`

`vec(dv)/dt=vec(domega)/dtxxvecr+vecomegaxxvec(dr)/dt`

where 

`(dvecomega)/dt=vecalpha,`

`(dr)/dt=vecv`

`(dvecv)/dt=veca`

`:.veca=vecalphaxxvecr+vecomegaxxvecv`
