A solid sphere is set into motion on a rough horizontal surface with a linear velocity v in the forward direction and an angular velocity v/R in the anticlockwise direction as shown in the figure. Find the linear speed of the sphere, when it stops rotating. A. `(v)/(5)`B. `(v)/(7)`C. `(3v)/(5)`D. `(3v)/(7)` |
