Question

In a one-dimensional collision, a particle of mass 2m collides with a particle of mass m at rest. If the particles stick together after the collision, then 1/n th fraction of the initial kinetic energy is lost in the collision. Find n

Answer 1

Answer:

Correct Answer is: (B) 1/3 Let initial velocity of 2m is u ∴ finally,the velocity of the combined mass will be, v = (2m)u / 2m + m = 2u/3 Read more on Sarthaks.com - https://www.sarthaks.com/565033/in-a-one-dimensional-collision-particle-of-mass-2m-collides-with-a-particle-of-mass-at-rest
