A300.0-kg speedboat is moving across a lake at 35.0 m/s. what is the momentum of the speedboat?

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.
