A particle of mass 0.1 kg is held between two rigid supports by two springs of force constant 8 N m^(-1) and 2 N m^(-1) . If the particle is displaced along the direction of length of the springs, its frequency of vibration is

Two springs have their force constant as K_(1) and K_(2)(K_(1)lt K_(2)) . When they are stretched by the same force:

A string of length 40 cm and weighing 10 g is attached to a spring at one end and to a fixed wall at the other end. The spring has a spring constant of 160 N m^-1 and is stretched by 1.0 cm. If a wave pulse is produced on the string near the wall, how much time will it take to reach the spring ?

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 :

Two springs have their force constant as k_(1) and k_(2) (k_(1) gt k_(2)) . When they are streched by the same force.

Two point masses of 3.0 kg and 1.0 kg are attached to opposite ends of a horizontal spring whose spring constant is 300 N m^(-1) as shown in the figure. The natural vibration frequency of the system is of the order of :
