Two blocks A and B are connected to each other by a string and a spring, the string passes over a frictionless pulley as shown in Block B slides over the horizontal surface of a stationary block C and the block. A slides along the vertical side of C, both with same uniform speed. The coefficient of friction between the surface of the blocks is 0.2 Force constant of the spring is 1960 N//m if the mass of block A is 2 kg calculate the mass of the block B and the energy stored in the spring.

In the two block spring system, force constant of spring is k = 6N/m. Spring is stretched by 12 cm and then left. Match the following.

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 . In the equilibrium position, speed of the block placed horizontally 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 m is initially moving to the right on a horizontal frictionless surface at a speed v. It then compresses a spring of spring constant k. At the instant when the kinetic energy of the block is equal to the potential energy of the spring, the spring is compressed a distance of :

The blocks ov mass m_(1)kg and m_(2)=2kg are connected by an ideal spring, rest on a rough horizontal surface. The spring is unstressed. The spring constant of spring is K=2N//m . The coefficient of friction between blocks and horizontal surface is mu=(1)/(2) . Now the left block is imparted a velocity u towards right as shown. The largest value of u( in m//s) such that the block of mass m_(2) never moves is ( Take g=10m//s^(2))

A constant force produces maximum velocity V on the block connected to the spring of force constant K as shown in the fig. When the force constant of spring becomes 4K the maximum velocity of the block is
