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 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 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 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 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 block of mass 1 kg is placed over a plank of mass 2 kg. The length of the plank is 2m. Coefficient of friction between the block and the plank is 0.5 and the ground over which plank is placed is smooth. A constant force F = 30 N is applied on the plank is horizontal direction. The time after which the block will separate from the plank is 73xx10^(-x)S the value of x is : (g = 10 m//s^(2))

A small block of mass 1kg is placed over a plank of mass 2kg. The length of the plank is 2 m. coefficient of friction between the block and the plnak is 0.5 and the ground over which plank in placed is smooth. A constant force F=30N is applied on the plank in horizontal direction. the time after which the block will separte from the plank is (g=10m//s^(2))

A uniform plank of Young's modulus Y is moved over a smooth horizontal surface by a constant horizontal force F. The area of cross section of the plank is A. The compressive strain on the plank in the direction of the force is

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)
