A block of mass `1kg` is kept on smooth floor of a truck. One end of a spring of force constant `100 N//m` is attached to the block and other end is attached to the body of truck as shown in the figure. At `t = 0`, truck begins to move with constant acceleration `2 m//s^(2)`. The amplitude of oscillation of block relative to the floor of truck is

One end of a spring of force constant k_1 is attached to the ceiling of an elevator. A block of mass 1.5kg is attached to the other end. Another spring of force constant k_2 is attached to the bottom of the mass and to the floor of the elevator as shown in figure. At equilibrium, the deformation in both the spring is equal and is 40cm . If the elevator moves with constant acceleration upward, the additional deformation in both the spring is 8cm . Find the elevator's accelerationn ( g=10ms^-2 ).

A block of mass M is kept on a rough horizontal surface and is attached with massless spring of force constant k .The minimum constant force applied on the other end of the spring to lift the block is

One end of an spring is connected with a smooth block with the other end with rear wall of ratio of a track qas shown in figure. initially, the system is at restif track start to its accelerate with a constant acceleration then the block (relative to track)

A block of mass m is kept on a rough horizontal surface and is attached with a massless spring of force constant k. The minimum constant force applied on the other end of the spring of lift the block is
