One end of a spring is rigidly fixed. A block attached to the free end of the spring is pulled through a distance `x_(0)`. On releasing the block, its amplitude of motion cannot exceed `+-x_(0)`. Why?

A source S emitting sound of 300 Hz is fixed of block A which is attached to free end of a spring S_A as shown in the figure. The detector D fixed on block B attached to the free end of spring S_B detects this sound. The blocks A and B are simultaneously displaced towards each other through of 1.0 m and then left to vibrate. Find the maximum and minimum frequencies of sound detected by D if the vibrational frequency of each block is 2 Hz (velocity of sound is 340 m/s).

A spring has natural length 40 cm and spring constant 500 N//m . A block of mass 1 kg is attached at one end of the spring and other end of the spring is attached to a ceiling. The block is relesed from the position, where the spring has length 45 cm .

A source S emitting sound of frequency 300Hz is fixed on block A which is attached to the free end of a spring S_(A) as shown in figure. The detector D fixed on block B attached to free end of spring S_(B) detects this sound. The blocks A and B are simultaneously displaced towards each other through a distance of 1.0m and then left to vibrate. The maximum and minimum frequencies of sound detected by D, if the vibrational frequency of each block is 2Hz are (Velocity of sound v=340m//s )

A source S emitting sound of frequency 288 Hz is fixed on block B which is attached to the free end of a spring S_(2) and an observer O is on block A which is attached to the free end of spring S_(1) as shown in the figure. The blocks A and B are simultaneously displaced towards each other through a distance of 0.5 m and then left to oscillate. If the angular velocity of each blocks is 40"rad"s^(-1) , then the maximum frequency observed by the observer is (speed of sound in air is 340 ms^(-1) )
