What is collision? Discuss types of collision.

What is reverse osmosis? Discuss one of its application?

When is a collision said to be a perfectly inelastic? A mass is moving with speed v collides inelastically with another identical mass at rest. After collision, the first mass moves with velocity frac(nu)(sqrt 3) in a direction perpendicular to the initial direction of motion. Find the speed of the second mass after collision.

Prove that the momentum is conserved in collision

Show that in one dimensional elastic collision of two particales of equal mass,the partical exchange velocities after collisions.

A mass m moving with a speed u collides on a similar stationary mass and sticks to it. What is the velocity after collision?

Is it possible to have a collision in which the whole of K.E is lost.

Show that in two demensional elastic I collision between two bodies of equal mass and one body initialy at rest, they move at an angle of frac(pi)(2) after collision.

Show that the amount of kinetic energy always decreases in perfectly inelastic collision in one dimension.

Two identical ball bearings in contact with each other and resting on a frictionless table are hit head-on by another ball bearing of the same mass moving initially with a speed VL If the collision is elastic, which of the following figure is a possible result after collision?

Define the co-efficient of restitution. A particle of a mass m moving with a velocity u struck head-on against another particle of mass Km at rest.After collision the particles move with velocities V1 and V2 respectively.If the collision is prefectly elastic.Prove that the loss of kinetic energyof the particle with mass m is maximum when k=1.
