Answer:
[tex]\boxed {\boxed {\sf D. \ 10 \ m/s}}[/tex]
Explanation:
Momentum can be found by multiplying mass by velocity.
[tex]p=mv[/tex]
If we rearrange this formula for velocity (v), then the formula becomes:
[tex]\frac{p}{m}=\frac{mv}{m}[/tex]
[tex]\frac{p}{m} =v[/tex]
We have to divide the momentum by the mass. The momentum is 150 kg*m/s and the mass is 15 kilograms.
[tex]p=150 \ kg*m/s\\m=15 \ kg[/tex]
Substitute the values into the formula.
[tex]\frac{150 \ kg *m/s}{15 \ kg} =v[/tex]
Divide. Note that the kilograms (kg) will cancel each other out.
[tex]10 \ m/s=v[/tex]
The velocity of the object is 10 meters per second.
