A marble 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?.

Explanation:

The momentum can be calculated as follows:

p = mv

Where m is the mass of the marble and v its velocity. Therefore:

p = 0.0015kg · 0.0005m/s = 0.0000075 kg·m/s = 7,5·10^{-6}kg·m/s

Note that we have converted the grams in kg and cm/s in m/s.

7.5 × 10⁻⁶ kgm/s.

Explanation:

Data:

Mass = 1.5 g => 0.0015 kg

Velocity = 0.5 cm/s => 0.005 m/s

Momentum = ?

Formula:

Momentum = Mass × Velocity

P =mv

Solution:

Momentum = 0.0015 kg × 0.005 m/s

Momentum = 0.0000075 kgm/s => 7.5 × 10⁻⁶ kgm/s

The magnitude of the marble's Momentum is 7.5 × 10⁻⁶ kgm/s.
