problem with solution about elastic and inelastic collisions in one and two dimensions

Elastic and Inelastic Collisions in One and Two Dimensions - 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' ..

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

A body of mass m 1 is moving with a velocity along X-axis. Let it suffer elastic collision with a stationary body of mass m 2 . The distance b, between the initial line of motion and a line parallel to it through the centre of the target body is called the..

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 ..

Head-on Elastic Collision [One Dimensional Elastic Collision] - It is that elastic collision in which the colliding bodies move along the same straight line before and after the collision. Consider two bodies ..

. Hence, steel arch is used instead, as steel arch is stronger than the stone arched bridge. 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 ..

Lyophobic sols are prepared by two methods. They are: 1) Condensation methods 2) Dispersion method..

The colloidal solutions prepared by various methods usually contain electrolytes and other soluble substances as impurities. These impurities if not removed can destabilize the sols. Impurities are removed by the following methods: 1) Dialysis 2) Ultra-filtra..

A body is said to be in motion if its position changes with respect to its surrounding. In order to completely describe the motion of such objects, we need to specify its position. For this, we need to know the position coordinates. In some cases, three position coordinates are required, in some ca..
