A) \[{{v}_{0}}+r\omega \]
B) \[{{v}_{0}}-r\omega \]
C) \[r\omega \]
D) \[{{v}_{0}}\]1
Correct Answer: A
Solution :
For pure rolling motion of sphere relative motion of Point of contact of sphere and plank should be zero. For this, the point of contact has a velocity equal to the velocity of plank. \[\therefore \]\[{{v}_{0}}={{v}_{CM}}-r\omega \] \[\therefore \]\[{{V}_{CM}}={{v}_{0}}+r\omega \] Hence, the correction option is [a].You need to login to perform this action.
