Laws Of Motion Question 214

Question: Two balls of masses m1 and m2 are 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 m1 travels a distance s1 and stops. If the coefficients of friction between the balls and ground are same, the mass m2 stops after travelling the distance [BHU 1994]

Options:

A) s2=m1m2s1

B) s2=m2m1s1

C) s2=m12m22s1

D) s2=m22m12s1

Show Answer

Answer:

Correct Answer: C

Solution:

We know that in the given condition s1m2

s2s1=(m1m2)2

therefore s2=(m1m2)2×s1
