For motion in two dimensions, the earlier kinematics equations must be expressed in vector form. For example, the average velocity vector is v = ( d f Velocity and acceleration vectors of an object moving in a circle. The following discussion summarizes the four different cases for acceleration in a planeA partial start from rest and has an acceleration of 2m/s^2 for 10s. After that ,it travels for 30s with constant speed and then undergoes a retardation of 4 km/s^2 and comes back to rest. The total distance covered by the particle is 1)650m 2)750m 3)700m. 4) 800m

The reason for the Maxwell-Boltzmann distribution of speeds (f(v)=4π[m/(2πkT)] 3/2 v 2 exp[-mv 2 /(2kT)]) is explained well at the hyperphysics web site. The answer to your question is that if two particles with equal mass and equal speed collide elastically, no kinetic energy is transferred.
