1.If the stretch in spring of force constant K IS DOUBLED FROM Y to 2Y. find the ration of initial to final force

If stretch in a spring of force constant k is doubled, calculate (a) ration of final to initial force in the spring. (b) ratio of elastic energies stored in the two cases. (c) work done in changing to the state of double stretch.

A spring of force constant k is cut into there equal part what is force constant of each part ?

A constant force produces maximum velocity V on the block connected to the spring of force constant K as shown in the fig. When the force constant of spring becomes 4K the maximum velocity of the block is

A spring of force constant k is cut into four equal parts. The force constant of each part will be

One-forth length of a spring of force constant K is cut away. The force constant of the remaining spring will be

A constant force produces maximum velocity V on the block connected to the spring of force constant K as shown in the figure. When the force constant of spring becomes 4K, the maximum velocity of the block is

As shown in the figure, two light springs of force constant k_(1) and k_(2) oscillate a block of mass m. Its effective force constant will be

When a mass M is attached to the spring of force constant k , then the spring stretches by . If the mass oscillates with amplitude l , what will be maximum potential energy stored in the spring
