Two blocks of masses `1 kg` and `3 kg` are moving with velocities `2 m//s` and `1 m//s` , respectively , as shown. If the spring constant is `75 N//m` , the maximum compression of the spring is

In the arrangements as shown, blocks A and B of the masses as shown move in the direction with velocities as indicated on a smooth surface. The spring constant is 300 N/m. find the maximum compression in the spring (approx).

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

A 2kg block is dropped from a height of 0.4 m on a spring of force constant 1960Nm^(-1) . The maximum compression of the spring is

A mass of 0.5 kg moving with a velocity of 1.5 m/s on a horizontal smooth surface, collides with a nearly weightless spring of force constant K=50N//m . The maximum compression of the spring would be:

Two blocks of masses m_(1)= 2 kg and m_(2) = 4 kg are moving in the same direction with speeds v_(1) = 6 m//s and v_(2) = 3 m//s , respectively on a frictionless surface as shown in the figure. An ideal spring with spring constant k = 30000 N//m is attached to the back side of m_(2) . Then the maximum compression of the spring after collision will be
