Dear Student,
- Applying conservation of momentum
(mv)bullet + (mv)planck = (mv)together
=> 10x1.5 + 0 = 100 X v
=> v = 0.15 m/sCheers!!Regards,Vikas (B. Tech. 4th year

Three identical balls are placed on a frictionless
horizontal surface touching each other. They stick to
each other because of adhesive. Another ball of same
radius and mass m is placed over the void created by
the three balls. Find the forces applied by the balls
kept on the floor to each other if the system remains
in equilibrium.
