Question

A spring of natural length 3 m and spring constant $9 N / m$ is having one end at origin and other end attached to a block of mass 1 kg . There is a wall at $x = 3 m$ . At $t = 0$ block is released from rest at $x = 1 m$ . Collision of block with wall is elastic. Which of the following gives position of block with time :-

Spring compress from NLP = 2m than release

Amplitude of the SHM = 2m.

& always SHM left side of NLP due to wall.

$\displaylines x - 3 = - 2∣ cos (ω t) ∣ x = 3 - 2∣ cos (ω t) ∣ ω = \frac{k}{m} = 9 = 3 x = 3 - 2∣ cos (3 t) ∣$
