Two blocks of mass 10 kg and 2 kg are co...

Two blocks of mass 10 kg and 2 kg are connected by an ideal spring of spring constant `K = 800 N//m` and the system is placed on a horizontal surface as shown.

The coefficient of friction between 10 kg block and surface is 0.5 but friction is absent between 2 kg and the surface. Initially blocks are at rest and spring is relaxed. The 2 kg block is displaced to elongate the spring by 1 cm and is then released. (a) Will 10 kg block move subsequently? (b) Draw a graph representing variation of magnitude of frictional force on 10 kg block with time. Time t is measured from that instant when 2 kg block is released to move.

Two blocks of mass 10 kg and 2 kg are connected by an ideal spring of spring constant 1000 N/m and the system is placed on a horizontal surface as shown. The coefficient of friction between 10 kg block and surface is 0.5 but friction is assumed to be absent between 2 kg and surface. Initially blocks are at rest and spring is unstretched then 2 kg block is displaced by 1 cm to elongate the spring then released. Then the graph representing magnitude of frictional force on 10 kg block and time t is : (Time t is measured from that instant when 2 kg block is released to move)
