Vedclass · Answer

(c) Momentum of one piece $ = \frac{M}{4} 	imes 3$

Momentum of the other piece $ = \frac{M}{4} 	imes 4$  

Resultant momentum $ = \sqrt {\frac{{9{M^2}}}{{16}} + {M^2}} = \frac{{5M}}{4}$

The third piece should also have the same momentum.

Let its velocity be $v$, then $\frac{{5M}}{4} = \frac{M}{2} 	imes v$

A body of mass $M$ at rest explodes into three pieces, two of which of mass $M/4$ each are thrown off in perpendicular directions with velocities of $3\, m/s$ and $4\, m/s$ respectively. The third piece will be thrown off with a velocity of .......... $m/s$
