A body of mass 1 kg initially at rest, explodes and breaks into three fragments of masses in the ratio 1 : 1 : 3 . The two pieces of equal mass fly off perpendicular to each other, with a speed of 15 m/s each. The speed of the heavier fragment is :
- \(5 \sqrt{2} \mathrm{~ms}^{-1}\)
- \(45 \mathrm{~ms}^{-1}\)
- \(5 \mathrm{~ms}^{-3}\)
- \(15 \mathrm{~ms}^{-1}\)
Answer
(A) 5 2 ~ms ^ -1
