Two balls of masses $$m1and$$ $$m2are$$ separated from each other by a powder charge placed between them. The whole system is at rest on the ground. Suddenly the powder charge explodes and masses are pushed apart. The mass $$m1travels$$ a distance $$s1and$$ stops. If the coefficients of friction between the balls and ground are same, the mass $$m2$$ stops after travelling the distance

Question

Two balls of masses $$m1and$$ $$m2are$$ separated from each other by a powder charge placed between them. The whole system is at rest on the ground. Suddenly the powder charge explodes and masses are pushed apart. The mass  $$m1travels$$ a distance $$s1and$$ stops. If the coefficients of friction between the balls and ground are same, the mass $$m2$$ stops after travelling the distance

from conservation of linear mometum they will have same momentum but in opposite directions their kinetic energy $$p22m$$  from work energy theorem  $$p22m=$$ μmgs s is inversely proportionoal to $$m2$$
