Find the acceleration of center of mass of the blocks of masses m_(1) and m_(2) (m_(1)gtm_(2)) in Atwood.s machine: |
|
Answer» SOLUTION :We know from Newton.s laws of motion magnitude of acceleration of each block is `a=((m_(1)-m_(2))/(m_(1)+m_(2)))G` Now acceleration of their C.M is `a_(cm)=(m_(1)a+m_(2)(-a))/(m_(1)+m_(2)),a_(cm)=((m_(1)-m_(2))/(m_(1)+m_(2)))a` `a_(cm)=((m_(1)-m_(2))/(m_(1)+m_(2)))((m_(1)-m_(2))/(m_(1)+m_(2)))g` `:.` ACCLERATION of centre of mass `a_(cm)=((m_(1)-m_(2))/(m_(1)+m_(2)))^(2)g` |
