Spring,Pulley & Friction

A block of mass m attached with a massless spring of force constant k The block is placed over a rought inclined surface for which the coefficient of friction is 0.5M is released from rest when the spring was unstretched The minimum to move the value of M required to move the block m up the plane is (neglect mass of spring and pulley and friction in pulley)

A block of mass m is attached with a massless spring of force constant K. the block is placed over a rough inclined surface for which the coefficient of friction is mu =3/4 find the minimum value of M required to move the block up the place. (Neglect mass of string and pulley. Ignore friction in pulley). .

A block of mass m is attached with a massless spring of force constant k. The block is placed over a rough inclined surface for which the coefficient of friction is mu=(3)/(4) . The minimum value of M required to move the block up the plane is (Neglect mass of string, mass of pulley and friction in pulley)

Find the time period of oscillation of block of mass m. Spring, and pulley are ideal. Spring constant is k.

There are tow identical spring each of spring constant k. here springs, pulley and rods are massless and the block has mass m . What is the extension of each spring at equilibrium?

A block of mass m is attached with a massless spring of force constant k . The block is placed over a fixed rought inclined surface for which the coefficient of friction is mu=(3)/(4) . The block of mass m is initially at rest . The block is mass M is released from rest with spring in unstretched state. The minimum value of M required to move the block up the plane is ( neglect mass of string and pulley and friction in pulley )

For shown situation find the maximum elongation in the spring. Neglect friction everywhere. Initiallthe blocks are at rest and spring is unstreched.

Consider the system shown below, with two equal masses m and a spring with spring constant K . The coefficient of friction between the left mass and horizontal table is mu=1//4 , and the pulley is frictionless. The spring connecting both the blocks is massless and inelastic. The system is held with the spring at its unstretched length and then released. If the string connecting both the masses is cut just at the instant both masses came to momentary rest for the first time in question 5, then maximum compression of spring during resulting motion is (Take mu=1//4 )
