Question

A bomb of mass 16 kg at rest explode into two pieces of masses 4 kg and 12kg . The velocity of the 12 kg mass is 4 m per second. The kinetic energy of other mass is a)144J b) 288J c)192J

Answer 1

(12×4/)/4=velocity
v=12
1/2×4×12×12=kinetic energy
228j=kinetic energy. plz mark brainlist answer
