# A body of mass (4m) is laying in x-y plane at rest. It suddenly explodes into three pieces. Two pieces, each of mass (m) move perpendicular to each other with equal speeds (). The total kinetic energy generated due to explosion is: Option 1) m2 Option 2) Option 3) 2 m2 Option 4) 4 m2

As we discussed in concept @7029

By conservation of linear momentum

As two masses of each of mass m move perpendicular to each other.

Total K.E generated =
