A lawn roller is a solid cylinder of mass M and radius R . As shown in the figure, it is pulled at its center by a horizontal force F and rolls without slipping on a horizontal surface. Then the

A lawn roller is a solid cylinder of mass M and radius R . As shown in the figure, it is pulled at its center by a

Options

Aacceleration of the cylinder is $\frac{2 F}{M}$
Bforce of friction acting on the cylinder is $\frac{2 F}{3 M}$
Ccoefficient of friction needed to prevent slipping is at least $\frac{F}{3 M g}$
Dminimum coefficient of friction to prevent slipping is $\frac{2 F}{3 M g}$

Correct answer

C. coefficient of friction needed to prevent slipping is at least $\frac{F}{3 M g}$
