problems involving elastic and inelastic collisions in one dimension

A Karate expert strikes a board of mass 0.14 kg and breaks it, with his fist of mass 0.70 kg. He then does the same to a 3.2 kg concrete block. The spring constant 'k' for bending are, 4.1 x 10 4 N/m for the board and 2.6 x 10 6 N/m for the block. Breaking occurs at a deflection 'd' of 16..

Elastic Collision in Two Dimensions (Oblique Collision) - If the colliding bodies do not move along the same straight line path, then the collision is said to be an oblique collision..

If the colliding bodies do not move along the same straight line path, then the collision is said to be an oblique collision..

A collision is said to be an inelastic collision if the kinetic energy is not conserved in the collision. However the momentum is conserved. The kinetic energy lost in the collision appears in the form of heat energy, sound energy or light energy. T..

It is that elastic collision in which the colliding bodies move along the same straight line before and after the collision..

A collision is said to be an elastic collision if both the kinetic energy and momentum are conserved in the collision. During collision, the bodies are deformed. However, they regain their original shape completely if the collision is ..

If the two bodies stick together after the collision, the collision is said to be perfectly inelastic. In this type of collision, the loss of kinetic energy is maximum but not complet..

The thickness of the metallic rope needed to lift a given load is decided using the knowledge of elastic limit of the material of the rope and the factor of safety. Electric poles are made hollow A hollow shaft is found to be stronger than a solid one because the torque required..
