Question

Calculate the momentum of a wooden model train car that has a mass of 5 kg and moves with a velocity of 10 m/s.

A) 50 kg m/s
B) 15 kg m/s
C) 5 kg m/s
D) 500 kg m/s

Answer 1

The momentum of a wooden model train car with a mass of 5 kg and a velocity of 10 m/s is calculated using the formula momentum (p) = mass (m) × velocity (v). The answer is 50 kg·m/s.

Step-by-step explanation:

To calculate the momentum of a wooden model train car with a given mass and velocity, we use the formula for linear momentum, which is the product of mass and velocity:

Momentum (p) = mass (m) × velocity (v).

Plugging in the values:

Momentum (p) = 5 kg × 10 m/s = 50 kg·m/s.

Therefore, the momentum of the model train car is 50 kg·m/s, which corresponds to option A).
