A block of mass m is on the smooth horizontal surface of a plank of mass M The plank is on smooth horizontal surface Now, a constant horizontal force F acts on M. Now, for a person standing on the ground:

A block of mass'm' it kept over the smooth surface of the plank of mass M. the plank of length l is kept over the smooth horizontal surface. A constant horizontal force F is applied onto the plank as shown in figure. Calculate the time after which the block falls off the plank?

A block of mass m is placed at rest on a smooth wedge of mass M placed at rest on a smooth horizontal surface. As the system is released

A block of mass m is placed at rest on a smooth wedge of mass M placed at rest on a smooth horizontal surface. As the system is released

A horizontal force F pushes wedge of mass M on a smooth horizontal surface. A block of mass m is stationary to the wedge, then:

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_(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)
