The acceleration of the 2 kg block if the free end of string is pulled with a force of 20 N as shown is

A block of mass 2kg is placed on a trolley of mass 20 kg free to move on a frictionless floor. What are the frictional force, accelerations of the block and trolley if the block is pulled by a force of 3 N ? The coefficient of friction between block and trolley is 0.25. What will be the values of all three if the block is pulled by 8 N force ? At what value of the applied force will the bodies just tend to separate ? [Hint : So long as the force applied does not produce the limiting frictional force the two will move with common acceleration. When the force applied exceeds that limiting value the block will move on the trolley with a different acceleration]

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 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.

In the arrangement shown in the fig, end A of the string is being pulled with a constant horizontal velocity of 6 m//s . The block is free to slide on the horizontal surface and all string segments are horizontal. Find the velocity of point P on the thread.

A block of mass 10 kg is hanging over a smooth and light pulley through a light string and the other end of the string is pulled down by a constant force F. The kinetic energy of the block increases by 20 J in 1 s

Three blocks of masses 2 kg , 3 kg and 5 kg are connected to each other with light string and are then placed on a frictionless surface as shown in the figure. The system is pulled by a force F= 10 N then tension T_(1)=
