Answer: The correct answer is 10,500 kg m/s.
Explanation:
The expression of the momentum in terms of mass and velocity is as follows;
p=mv
Here, m is the mass of the object and v is the velocity.
It is given in the problem that a 300.0-kg speedboat is moving across a lake at 35.0 m/s.
Put m= 300 kg and v= 35 m/s in the above expression.
p=(300)(35)
p= 10,500 kg m/s
Therefore, the momentum of the speedboat is 10,500 kg m/s.
