Question

2 magnetic gliders of mass m and M (M>m) have an elastic collision (M was at rest)

write the law of conservation Off momentum applied to this system

write the law Off conservation Off energy for the system

Answer 1

Let magnetic glider of mass "m" initially moves with velocity "v" while M is at rest.

After elastic collision between them they move with final velocity v_1f and v_2f.

_{by law of conservation of momentum-}

   _{-------------(1)}

_{Using law of conservation of kinetic energy in an elastic collision-}

_{--------------(2)}
