A plank with a mass M= 6.00 kg
rests on top of two identical solid cylindrical rollers that have R=5.00 cm
and m=2.00 kg
(figure). The plank is pulled by a constant horizontal force →F
of magnitude 6.00 N
applied to the end of the plank and perpendicular to the axes of the cylinders(which are parallel). The cylinders roll without slipping on a flat surface. There is also no slipping between the cylinders and the plank. All surfaces are rough.
The initial acceleration of the plank at the moment when the rollers are equidistant from the ends of the plank is m/s2
