In figure a spring with k = 168 N//m is ...

In figure a spring with `k = 168 N//m` is in its relaxed length and is at the top of a frictionless incline of angle `theta = 37^(@)`. The lower end of the incline is at distance D = 1 m from the end of the spring. A small blcok of mass 2 kg is pushed against the spring until the spring is compressed by 0.2 m and released from rest.

What is the speed of the block when it reaches the lower end of the incline?

In figure a spring with k = 168 N//m is in its relaxed length and is at the top of a frictionless incline of angle theta = 37^(@) . The lower end of the incline is at distance D = 1 m from the end of the spring. A small blcok of mass 2 kg is pushed against the spring until the spring is compressed by 0.2 m and released from rest. What is the speed of the block at the instant the spring returns to its relaxed length (which is when the block loses contact with the spring)?

In the figure shown, all surfaces are smooth and force constant of spring is 10N//m . Block of mass (2 kg) is attaced with the spring. The spring is compressed by (2m) and then released. Find the maximum distance d travelled by the block over the inclined plane. Take g=10m//s^(2) . .

A massless spring of natural length of 0.5 m and spring constant 50 N/m has one end fixed and the other end attached to a mass of 250 g. The spring mass system is on a smooth floor. The mass is pulled until the length of the spring is 0.6 m and then released from rest. The kinetic energy of the mass when the length of the spring is 0.5 m is

The masses in figure slide on a frictionless table. m_(1) but not m_(2) , is fastened to the spring. If now m_(1) and m_(2) are pushed to the left , so that the spring is compressed a distance d , what will be the amplitude of the oscillation of m_(1) after the spring system is released ?

The block of mass m is released when the spring was in its natrual length. Spring constant is k. Find the maximum elongation of the spring.

A disc of mass m is connected with an ideal spring of stiffness k . If it is released from rest, it rolls without sliding on an inclination plane. The maximum elongation of the spring is:

In the figure shown a block of masss m is atteched at ends of two spring The other ends of the spring are fixed The mass m is released in the vertical plane when the spring are released The velocity of the block is maximum when

Two blocks of masses m and m' are connected by a light spring on a horizontal frictionless table . The spring is compressed and then released . Find the ratio of acceleration of masses .

An ideal massless spring S can compressed 1.0 m in equilibrium by a force of 1000 N . This same spring is placed at the bottom of a friction less inclined plane which makes an angle theta =30^@ with the horizontal. A (10 kg) mass (m) is released from rest at the top of the incline and and is brought to rest momentarily after compressing the spring by 2 m. if g =10 ms^(-1) , what is the speed of just before it touches the spring? .

Figure. shows a rough horizontal plane which ends in a vertical wall, to which a spring is connected, having a force constant k. Initially spring is in its relaxed state. A block of mass m starts with an initial velocity u towards the spring from a distance l_(0) from the end of spring shown. When block strikes at the end ofthe spring, it compresses the spring and comes to rest. Find the maximum compression in the spring. The friction coefficient between the block and the floor is mu ..
