Final Answer:
The magnitude of the momentum of the truck can be calculated using the formula momentum = mass × velocity, where m is the mass and v is the velocity. In this case, the mass of the truck is 11,000 kg, and its speed is 12.0 m/s. The magnitude of the momentum of the truck is 132,000 kg*m/s.
Step-by-step explanation:
Momentum is the product of an object's mass and its velocity. The formula for momentum (p) is given by p = m * v, where m is the mass and v is the velocity. In this case, the mass of the truck is 11,000 kg, and its speed is 12.0 m/s.
Substitute these values into the formula:
p = 11,000 kg * 12.0 m/s
p = 132,000 kg*m/s.
So, the magnitude of the momentum of the truck is 132,000 kg*m/s. Momentum is a vector quantity, and its direction is the same as the direction of the velocity. In this context, since the problem only provides the magnitude, the direction of the momentum is not specified.
