A spring block system is placed on a rough horizontal floor. The block is pulled towards right to give spring an eleongation less than (2 mu mg)/(K) but more than (mu mg)/(K) and released. Which of the following Jaws/principles of physics can be applied on the spring block system ?

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 0.500 kg block is attached to a spring with length 0.60m and force constant k=40.0 N//m . The mass of the spring is negligible. You pull the block to the right along the surgace with a constant horizontal force F=20.0 N .
