One end of a spring of force constant K is fixed to a vertical wall and other to a body of mass m resting on smooth horizontal surface. There is another wall at a distance of 3 x 0 from the body. If all the collisions are elastic and spring is compressed by 2 x 0 and released, then the time period of oscillation is

Options

  1. A5 π 3 m K
  2. B5 π 4 m K
  3. C3 π 2 m K
  4. D4 π 3 m K

Correct answer

A. 5 π 3 m K

Step-by-step solution

T = 2 π m k t = T 2 + 2 × T 6 = 5 T 6
