A particle of mass $$1$$ kg is thrown vertically upward with speed $$100$$ $$m/s$$. After $$5$$ $$sec$$ it explodes into two parts. One part of mass $$400$$ g comes back with speed $$25$$ $$m/s$$, what is the speed of the other part just after explosion? (g=10$$ $$m/s2)

Question

A particle of mass $$1$$ kg is thrown vertically upward with speed $$100$$ $$m/s$$. After $$5$$ $$sec$$ it  explodes into two parts. One part of mass $$400$$ g comes back with speed $$25$$ $$m/s$$, what is the speed of the other part just after explosion? (g=10$$ $$m/s2)

v $$=$$ u – gt $$=$$ $$100$$ – $$10(5)$$ $$=$$ $$100$$ – $$50$$ $$=$$ $$50m/smv$$ $$=$$ $$m1v1$$ $$+$$ $$m2v21000$$ x $$50$$ $$=$$ (400)(-25) $$+$$ $$600v250000$$ $$=$$ $$-10000$$ $$+$$ $$600v260$$,$$000$$ $$=$$ $$600v2There$$ fore $$v2$$ $$=$$ $$100$$ m $$/$$ s

A particle of mass 1 kg is thrown vertically upward with speed 100 m/s. After 5 sec it explodes into two parts. One part of mass 400 g comes back with speed 25 m/s, what is the speed of the other part just after explosion? (g=10 m/s²)
