IN a headon collision between two particles, is it necessary that the particles will acquire a common velocity at least for one instant?

A particle moves in straight line. Acceleration of particle changes with velocity as showns in graph:

Three particles A, B, Care located at the comers of an equilateral triangle as shown in figure. Each of the particle is moving with velocity v. Then at the instant shown, the relative angular velocity of

In a head on collision between two identical particles A and B moving on a horizontal surface, B is stationary and A has momentum P_(0) before impact. Due to the impact, A recieives an impulse I. Then coefficient of restitution between the two is :

In a head on collision between two identical particles A and B moving on a horizontal surface, B is stationary and A has momentium P_(0) before impact. Due to the impact, A receives an impulse I. Then coefficient of restitution between the two is :

In a one dimensional collision between two identical particles A and B, B is stationary and A has momentum p before impact. During impact, B given J to A.

Assertion: In successive time intervals if the average velocities of a particle are equal then the particle must be moving with constant velocity. Reason: When a particle moves with uniform velocity, its displacement always increases with time.

A particle of mass m moving with velocity v makes head-on elastic collision with a sationary particle of mass 2m. Kinetic energy lost by the lighter particle during period of deformation is

In a collinear collision a particle with an intial speed v_(0) strike a stationary particle of the same mass. If the final total kinetic energy is 50 % greater than the original kinetic energy the magnitude of the relative velocity between the two particles after collision is .

Statement-I : If two particles, moving with constant velocities are to meet, the relative velocity must be along the line joining the two particles. Statement-II : Relative velocity means motion of one particle as viewed from the other.

A particle is projected horizontally as shown from the rim of a large hemispherical bowl. The displacement of the particle when it strikes the bowl the first time is R. Find the velocity of the particle at that instant and the time taken.
