Final answer:
The momentum of the 4,000-kilogram truck traveling at 10.0 m/s is 40,000 kg*m/s.
Step-by-step explanation:
The momentum of an object is defined as the product of its mass and velocity. The formula for momentum is:
Momentum = mass x velocity
In this case, the truck has a mass of 4,000 kilograms and is traveling at 10.0 m/s. Therefore, its momentum can be calculated as:
Momentum = 4,000 kg x 10.0 m/s = 40,000 kg*m/s
So, the momentum of the truck is 40,000 kg*m/s.
