A block of mass M is pulled on a smooth horizontal table by a string making an angle theta with the horizontal as shown in figure. If the acceleration of the block is a , find the force applied by the string and by the table N on the block.

A block of mass m slides along a frictionless surface as shown in the figure. If it is releases from rest from A what is its speed at B?

A block of mass 2.5 kg is kept on a rough horizontal surface. It is found that the block does not slide if a horizontal force less than 15 N is applied to it. Also it is found that it takes 5 seconds to slide through the first 10 m if a horizontal force of 15 N is applied and the block is gently pushed to start the motion. Taking g=10 m/s^2 , calculate the coefficient of static and kinetic friction between the block and the surface.
