Final answer:
The momentum of a 36,000 kg semi traveling north on Interstate 95 at 30 m/s is 1,080,000 kg·m/s.
Step-by-step explanation:
The momentum of a 36,000 kg semi traveling north at 30 m/s is 1,080,000 kg·m/s. Momentum, a vector quantity, is the product of an object's mass and velocity. In this case, the large mass of the semi combined with its substantial velocity results in a significant momentum. The direction (north) emphasizes the vector nature of momentum, indicating the motion's orientation. Understanding an object's momentum is crucial in analyzing and predicting its behavior in collisions or interactions, with larger masses or higher velocities leading to increased momentum, influencing the dynamics of the system.,
we can use the formula for momentum: momentum = mass x velocity.
Therefore, the momentum of the semi is:
momentum = 36,000 kg x 30 m/s = 1,080,000 kg·m/s
