A shell of mass 10kg flying horizontally with a velocity of 36kmph explodes in air into two fragments .

The larger fragment has a velocity of 25ms^-1 and directed in the same direction as the initial velocity of the shell. The smaller fragment has a velocity of 12.5ms^-2in the opposite direction . find the masses of the fragments…………………….

Dear student,

Apply conservation of momentum

m1u1=m1v1+m2v2

Apply conservation of energy

1/2mu1^2=1/2m1v1^2+1/2m2v2^2

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.
