Two masses are connected by a spring as shown in the figure. One of the masses was given velocity v = 2 k, as shown in figure where 'k' is the spring constant. Then maximum extension in the spring will be

A block of mass m moving with velocity v_(0) on a smooth horizontal surface hits the spring of constant k as shown. The maximum compression in spring is

The figure shows two blocks of mass m each, connected by an ideal unstretched spring and then placed on a frictionless floor. If the blocks are given velocities v_(0) and 2v_(0) as shown, then the maximum extension in the spring is

A block of mass m moving with velocity v_(0) on a smooth horizontal surface hits the spring of constant k as shown. Two maximum compression in spring is

The two blocks A and B of same mass connected to a spring and placed on a smooth surface. They are given velocities (as shown in the figure) when the spring is in its natural length :

A block of mass 20 kg is hung with the help of ideal string, pulleys and spring (Spring constant k = 1000 N/m) as shown in figure. If block is in equilibrium position then extension in the spring will be (g = 10 ms^-2)

Two identical blocks of mass m , each are connected by a spring as shownin the figure. At any instant of time t=0 , one block is given a velocity v_(1) and other is given a velocity v_(2)(v_(1)gtv_(2)) in the same direction simultaneously as shown in the figure. Find the maximum energy stored in the spring.

Two blocks of masses m and M connected by a spring are placed on frictionless horizontal ground. When the spring is relaxed, a constant force F is applied as shown. Find maximum extension of the spring during subsequent motion.
