Answer:
Comparison has been made.
Explanation:
Consider perfectly inelastic collision.Two masses of m1 and m2 with initial velocities u1 and u2 before colliding, stick together after collision and move with common speed v. then according to the rule of momentum preservation
m1u1+m2u2= (m1+m2)v
If u1 and u2 are known the final common velocity can be determined
Initial kinetic energy is
The collion here is perfectly inelastic this means kinectic energy is not conserved. Therefore, initial kinectic energy is not equal to final kinectic.
