Question
A body of mass (4m) is lying in x-y plane at rest. It suddenly explodes into three pieces. Two pieces each of mass (m) move perpendicular to each other withequal speeds (v). The total kinetic energy generated due to explosion is
Options
A.mv2
B.
mv2
mv2C.2mv2
D.4mv2
Solution
Initial momentum = Pi = 0
Final momentum Pf = 0 =
⇒ P3 = mv√2
Total KE =
Final momentum Pf = 0 =
⇒ P3 = mv√2
Total KE =
