Question

In a collinear collision can final kinetic energy be greater than the initial kinetic energy

Answer 1

In a collinear collision , a particle with an initial speed V strikes 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 the collision is':-) --



Momentum is conserved, because the total momentum of both objects before and after the collision is the same. However, kinetic energy is not conserved. Some of the kinetic energy is converted into sound, heat, and deformation of the objects. A high speed car collision is an inelastic collision.
