Question

what is one dimensional elastic Collison ? Derive the formula of velocities of bodies after such type of Collison​

Answer 1

An elastic collision is one that conserves internal kinetic energy. Conservation of kinetic energy and momentum together allow the final velocities to be calculated in terms of initial velocities and masses in one dimensional two-body collisions.

If two particles are involved in an elastic collision, the velocity of the second particle after collision can be expressed as:

v2f = 2⋅

m1(m2 + m1)v1i + (m2−m1)(m2+m1)v2i v 2 f = 2

m1( m2 + m1 )v1i + (m2 − m1)(m2 + m1)v2i

PLEASE MARK IT AS BRAINLIEST..

Answer 2

Answer:

an elastic collision which takes place in one dimension is called one dimensional elastic collision

m1v1 + m2v2 = m1v1' + m2v2'
