Question

"A 4,000-kilogram truck travels in a straight line at 10.0 m/s. What is its momentum?

a. 400 kg*m/s
b. 40000 m/s
c. 400 m/s
d. 40000 kg*m/s"

Answer 1

To find the momentum of the truck, which has a mass of 4,000 kg and is moving at 10.0 m/s, use the formula p = m * v. Multiplying the mass by velocity yields a momentum of 40,000 kg•m/s. The correct answer is d. 40,000 kg•m/s.

Step-by-step explanation:

The question is about finding the momentum of a truck. The formula for the momentum (p) of an object is given by p = mass (m) times velocity (v), p = m * v. For a truck with a mass of 4,000 kilograms traveling at a velocity of 10.0 meters per second, the momentum can be calculated as follows:

• Mass of the truck, m = 4,000 kg
• Velocity of the truck, v = 10.0 m/s

Now, we use the formula to calculate the momentum:

p = m * v

p = 4,000 kg * 10.0 m/s

p = 40,000 kg•m/s

Therefore, the correct answer is d. 40,000 kg•m/s.
