A 1 kg block attached to a spring vibrates with a frequency of 1 Hz on a frictionless horizontal table. Two springs identical to the original spring are attached in parallel to an 8 kg block placed on the same table. So, the frequency of vibration of the 8 kg block is
A block is placed on a frictionless horizontal table. The mass of the block is m and springs are attached on either side with force constants K_(1) and K_(2) . If the block is displaced a little and left to oscillate, then the angular frequency of oscillation will be
Two spring are connected toa block of mass M placed a frictionless surface as shown if both the spring have a spring constant k the frequency of oscillation block is
A block of mass 2kg is attached with a spring of spring constant 4000Nm^-1 and the system is kept on smooth horizontal table. The other end of the spring is attached with a wall. Initially spring is stretched by 5cm from its natural position and the block is at rest. Now suddenly an impulse of 4kg-ms^-1 is given to the block towards the wall. Find the velocity of the block when spring acquires its natural length
A block of mass 2kg is attached with a spring of spring constant 4000Nm^-1 and the system is kept on smooth horizontal table. The other end of the spring is attached with a wall. Initially spring is stretched by 5cm from its natural position and the block is at rest. Now suddenly an impulse of 4kg-ms^-1 is given to the block towards the wall. Approximate distance travelled by the block when it comes to rest for a second time (not including the initial one) will be (Take sqrt(45)=6.70 )
A mass of 1 kg attached to the bottom of a spring has a certain frequency of vibration. The following mass has to be added to it in order to reduce the frequency by half :

Assertion: A block of small m attached to a stiff spring will have large oscillation frequency. Reason: Stiff springs have high value of spring constant.
A block of mss m is placed on a level frictionless table. The block is attached to a horizontally aligned spring fixed with its other end and is vibrating in a horizontal with the pariod T . Suddenly at the instant of time when the spring comes to the position of euilibrium and becomes unstretched the block disconnects form the spring and continues sliding across the frictionless surface away from the until it encounters loop of radius R . What must be the amplitude of vibrations of the block s on the spring in order for the block to complets one loop without falling down?
