Question

A body of mass $4m$ at rest explodes into three pieces. Two of the pieces each of mass $m$ move with a speed $v$ each in mutually perpendicular directions. The total kinetic energy released is:

• A. $\frac{1}{2}m{v}^2$
• B. $m{v}^2$
• C. $\frac{3}{2}m{v}^2$
• D. $\frac{5}{2}m{v}^2$

Answer 1

The correct option is C $\frac{3}{2}m{v}^2$
