Final answer:
To calculate the momentum of the truck, we can use the equation p = mv. Given that the mass of the truck is 2,000 kg and the velocity is 35 m/s, the momentum of the truck is 70,000 kg*m/s.
Step-by-step explanation:
This asks for the calculation of the momentum of a tractor-trailer truck with a given mass and velocity. Momentum (ℙ) is given by the product of an object's mass (m) and its velocity (v), as defined by the equation ℙ = mv. In this case, the mass of the truck is 2,000 kg and the velocity is 35 m/s. Therefore, the momentum of the truck can be calculated as follows: ℙ = mv, ℙ = (2,000 kg)(35 m/s), ℙ = 70,000 kg·m/s. Hence, the momentum of the truck is 70,000 kg·m/s.
