Question

Show all work for the following problem, including formula, number substitution, and answerwith correct units.If the momentum of a car is 287 kg*m/s and the car is moving with a velocity 19 m/s, what isthe mass of the car?

Answer 1

Answer:

15.1 kg

Explanation:

The momentum of the car can be calculated as mass times velocity, so

$\rho=mv$

Where m is the mass and v is the velocity. Solving for m, we get

$m=\frac{\rho}{v}$

Now, we can replace ρ = 287 kg m/s and v = 19 m/s

$m=\frac{287\text{ kg m/s}}{19\text{ m/s}}=15.1\text{ kg}$

Therefore, the mass of the car is 15.1 kg
