Two identical steel cubes (masses 50g, side 1cm) collide head-on face to face with a speed of 10cm/s each. Find the maximum compression of each. Young’s modulus for steel = Y= 2 × 1011 N/m2.
From Hooke’s law, ,
Where F = Force,
A= Area of cross section
Y= young’s modulus
L=initial length of the cube
Δ L=change in length
Kinetic energy of both boxes K.E.
Now, the kinetic energy gets converted to potential energy due to compression and,
Now, P.E = K.E

An engine is attached to a wagon through a shock absorber of length 1.5m. The system with a total mass of 50,000 kg is moving with a speed of 36 km h-1 when the brakes are applied to bring it to rest. In the process of the system being brought to rest, the spring of the shock absorber gets compressed by 1.0 m. If 90% of energy of the wagon is lost due to friction, calculate the spring constant.Physics - Exemplar
Two springs A and B (kA = 2kB) are stretched by applying forces of equal magnitudes at the four ends. If the energy stored in A is E. that in B isHC Verma - Concepts of Physics Part 1
Consider the situation of the previous problem. Suppose the block of mass m1 is pulled by a constant force F1, and the other block is pulled by a constant force F2. Find the maximum elongation that the spring will suffer.HC Verma - Concepts of Physics Part 1
Consider one mole of perfect gas in a cylinder of unit cross section with a piston attached (Fig. 12.12). A spring (spring constant k) is attached (unstretched length L) to the piston and to the bottom of the cylinder. Initially the spring is unstretched and the gas is in equilibrium. A certain amount of heat Q is supplied to the gas causing an increase of volume from Vo to V1.
(a) What is the initial pressure of the system?
(b) What is the final pressure of the system?
(c) Using the first law of thermodynamics, write down a relation between Q, Pa, V, Vo and k.

Two equal masses are attached to the two ends of a spring of spring constant k. The masses are pulled out symmetrically to stretch the spring by a length x over its natural length. The work done by the spring on each mass isHC Verma - Concepts of Physics Part 1
Two blocks of masses m1 and m2 are connected by a spring of spring constant k (figure 9-E15). The block of mass m2 is given a sharp impulse so that it acquires a velocity u0 towards right. Find (a) the velocity of the center of mass, (b) the maximum elongation that the spring will suffer.
