A block of mass `1 kg` moves towards a spring of force constant `10 N//m`. The spring is massless and unstretched. The coeffcient of friction between block and surface is `0.30`. After compressing the spring, block does not return back : `(g = 10 m//s)`.

1 kg block collides with a horizontal massless spring of force constant 2 N//m . The block compresses the spring by 4m. If the coefficient of kinetic friction between the block and the· surface is 0.25, what was the speed of the block at the instant of collision? (take g = 10 m//s^(2) )

A block mass m = 2 kg is moving with velocity v_(0) towards a massless unstretched spring of the force constant k = 10 N//m . Coefficient of friction between the block and the ground is mu = 0.2 . Find the maximum value of v_(0) so that after pressing the spring the block does not return back but stops there permanently.

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)

A block of mass m is attached to one end of a mass less spring of spring constant k. the other end of spring is fixed to a wall the block can move on a horizontal rough surface.

A block of mass 0.18 kg is attached to a spring of force constant 2N/m. The coefficient of friction between the block and the floor is 0.1. Initially, the block is at rest and the spring is unstretched. An impulse is given to the block. The block slides a distance of 0.06 m and comes to rest for the first time. The initial velocity of the block in m/s is v=N/10. Then, N is
