The velocity of the object will be "12 m/sec".
The given values are:
Mass of object,
Momentum,
As we know,
→ [tex]Momentum = Mass \ of \ object\times Velocity[/tex]
or,
→ [tex]Velocity = \frac{Momentum}{Mass \ of \ object}[/tex]
By substituting the given values, we get
→ [tex]= \frac{600}{50}[/tex]
→ [tex]= 12 \ m/sec[/tex]
Thus the above answer is right.
