A spring-block system is resting on a frictionless floor as shown in the figure. The spring constant is `2.0Nm^(-1)` and the mass of the block is 2.0 kg. Ignore the mass of the spring. Initially the spring is in an unstretched condition. Another block of mass 1.0 kg moving with a speed of `2.0ms^(-1)` collides elastically with the first block. The collision is such that the 2.0 kg block does not hit the wall. The distance, in metres, between the two blocks when the spring returns to its unstretched position for the first time after the collision is

A spring-block system is resting on a frictionless floor as shown in the figure. The spring constant is 2.0 N m^(–1) and the mass of the block is 2.0 kg. Ignore the mass of the spring. Initially the spring is in an unstretched condition. Another block of mass 1.0 kg moving with a speed of 2.0 m s^(–1) collides elastically with the first block. The collision is such that the 2.0 kg block does not hit the wall. The distance, in metres, between the two blocks when the spring returns to its unstretched position for the first time after the collision is _________.

A block of mass 1 kg moving with a speed of 4 ms^(-1) , collides with another block of mass 2 kg which is at rest. The lighter block comes to rest after collision. The loss in KE of the system is

A block of mass 1 kg moving with a speed of 4 ms^(-1) , collides with another block of mass 2 kg which is at rest. If the lighter block comes to rest after collision, then the speed of the heavier body is

A constant force F is applied on a spring block system as shown in figure. The mass of the block is m and spring constant is k. The block is placed over a smooth surface. Initially the spring was unstretched. Choose the correct alternative(s)

A block of mass 8 kg is released from the top of an inclined smooth surface as shown in figure. If spring constant of spring is 200 Nm^(-1) and block comes to rest after compressing spring by 1 m then find the distance travelled by block before it comes to rest

If the force constant of spring is 50Nm^(-1) , find mass of the block, if it an rests in the given situation (g=10ms^(-2) ).

A block A of mass 2 kg rests on a horizontal surface. Another block B of mass 1 kg moving at a speed of m/s when at a distance of 16 cm from A. collides elastically with A. The coefficeint of friction between the horizontal surface and earth of the blocks is 0.2. Then (g = 10 m//s^(2))

A 1kg block situated on a rough incline is connected to a spring of spring constant 100Nm^(-1) as shown in figure,. The block is released from rest with the spring in the unstretched position. The block moves 10cm down the incline before coming to rest. Find the coefficient of friction between the block and the incline. Assume that the spring has negligible mass and the pulley is frictionless.

The system is released from rest with both the springs in unstretched positions. Mass of each block is 1 kg and force constant of each spring is 10 N//m . Extension of horizontal spring in equilibrium is
