A dog with mass M has its string attached to one end of a spring which runs without friction along a horizontal overhead rod. The other end of the springs is fixed to a wall The spring constant is K. The string is massless and inextensible and it maintains a constant angle `theta` with the overhead rod, even when the dog moves. There is friction with coefficient mu between the dog and the gound What is the maximum distance (in cm) that the dog moving slowly can stretch the spring beyond its natural length? Use M=30 kg,`K=400N//m and mu=1/3`

A

A man with mass M has its string'.attached to one end. of a spring which can move without friction along a horizontal, overhead fixed rod. The other end of the spring is fixed to a, wall. The spring constant is k. The string is massless and inextensible and it maintains a constant angle theta with the, overhead rod, even when the man moves. There is friction, iwith coefficient mu between the man and the ground. What is, the maximum distance (in m ) that the man moving slowly can stretch the spring beyond its natural length?

A block of mass m, attached to a spring of spring constant k, oscilltes on a smooth horizontal table. The other end of the spring is fixed to a wall. If it has speed v when the spring is at its naturla lenth, how far will it move on the table before coming to an instantaneous rest?

A block of mass m, attacted to a string of spring constant k, oscillates on a smooth horizontal table. The other end of the spring is fixed to a wall. The block has a speed v when the spring is at its natural length. Before coming to an instantaneous rest. If the block moves a distance x from the mean position, then

A bead of mass m is attached to one end of a spring of natural length R and spring constant K=((sqrt(3)+1)mg)/(R ) . The other end of the spring is fixed at a point A on a smooth vertical ring of radius R as shown in fig. The normal reaction at B just after it is released to move is

A ring of mass m is attached to a horizontal spring of spring constant k and natural length l_0 . The other end of the spring is fixed and the ring can slide on a horizontal rod as shown. Now the ring is shifted to position B and released Find the speed of the ring when the spring attains its natural length.

A bead of mass 'm' is attached to one end of a spring of natural length R & spring constant k = ((sqrt3 + 1))/(R) . The other end of the spring is fixed at point A on a smooth vertical ring of radius R as shown. The normal reaction at B just after it is released to move is

A block of mass 'm' is attached to a spring in natural length of spring constant 'k' . The other end A of the spring is moved with a constat velocity v away from the block . Find the maximum extension in the spring.

A small block of mass m=1kg is attached with one end of the spring of force constant K=110Nm^-1 . Other end of the spring is fixed to a rough plane having coefficient of friction mu=0.2 . The spring is kept in its natural length by an inextensible thread ties between its ends as shown in figure. If the thread is burnt, calculate the elongation of the spring when the block attains static equilibrium position.

A block of mass M is kept on a rough horizontal surface and is attached with massless spring of force constant k .The minimum constant force applied on the other end of the spring to lift the block is
