Final answer:
The momentum of a 4000 kg truck traveling at 10.0 m/s is calculated using the equation p = mv, resulting in a momentum of 40000 kg·m/s.
Step-by-step explanation:
To find the momentum of the truck, we will use the equation p = mv, where p is momentum, m is mass, and v is velocity. In this case, the mass (m) of the truck is 4000 kg, and its velocity (v) is 10.0 m/s. Substituting these values into the equation:
p = mv = 4000 kg × 10.0 m/s = 40000 kg·m/s
Therefore, the momentum of the truck is 40000 kg·m/s.
