Amarble with a mass of 1.5 grams rolls at a constant rate of 0.50 cm/s across a table. what is the magnitude of the marble's momentum?

7.5×10⁻⁶ kg m/s

Explanation:

The momentum of a body is given by the product its mass and velocity with which the object is moving.

P = m v

where m is the mass and v is the velocity

It is given that:

The mass of the marble is m = 1.5 g = 0.0015 kg

The velocity of the marble is v = 0.50 cm/s = 0.005 m/s

P = 0.0015 kg×0.005 m/s = 7.5×10⁻⁶ kg m/s

Thus, the magnitude of the marble's momentum
