A plank of mass `m_1` with a uniform sphere of mass `m_2` placed on it rests on a smooth horizontal plane. A constant horizontal force F is applied to the plank. With what acceleration will the plank and the centre of the sphere move provided there is no sliding between the plank and the sphere?

A plank of mass m_(1) with a sphere of mass m_(2) on it rests on a smooth horizontal surface. A canstant horizontal force F is applied to the plank. With what sliding between the plank and the sphere? [hint: Rel vel. Of the lowest point v-(2) + epsilonR -v_(1) =0 for no sliding)

A uniform sphere is placed on a smooth horizontal surface and a horizontal force F is applied on it at a distance h above the surface. The acceleration of the centre :

A plank with a uniform sphere placed on it. Rests on a smooth horizontal plane. Plank is pulled to right by a constant force F . It the sphere does not slip over the plank. .

A plank of mass m_(1) with a uniform solid sphere of mass m_(2) placed on it rests and a force F is applied to the plank. The acceleration of the plank provided there is no sliding between the plank and the sphere is (F/(m_(1)+n/7m_(2))) then the value of n is

A plank of mass m_1 with a bar of mass m_2 placed on it lies on a smooth horizontal plane. A horizontal force growing with time t as F^'=at (a is constant) is applied to the bar. Find how the accelerations of the plank w_1 and of the bar w_2 depend on t, if the coefficient of friction between the plank and the bar is equal to k. Draw the approximate plots of these dependences.

A plank with a uniform sphere placed on it rests on a smooth horizontal plane. The plank is pulled to the right by a constant force F . It the sphere does not slip over the plank, then

A plank with a uniform sphere placed on it resting on a smooth horizontal plane. Plank is pulled to right by a constant force F . If sphere does not slip over the plank. Which of the following is incorrect?

A sphere of mass m and radius r is placed on a rough plank of mass M . The system is placed on a smooth horizontal surface. A constant force F is applied on the plank such that the sphere rolls purely on the plank. Find the acceleration of the sphere.

A plank of mass M is placed on a rough horizontal surface and a contant horizontal force F is applied on it . A man of mass m runs on the plank find the range of acceleration of the man that the plank does not move on the surface is mu .Assume that the does not slip on the plank

A plank of mass M is moving on a smooth horizontal surface with speed 'v_(0)' . At t=0 a sphere of mass 'm' and radius 'r' is gently placed on it and simultaneously a constant horizontal force 'F' is applied on the plank in the opposite direction of v_(0) . Find the time at which sphere starts rolling on the plank. The coefficient of friction between the plank and the sphere is mu .
