A planned high-speed train between Houston and Dallas will travel a distance of 386 kilometers in 5.40 × 103 seconds. What is the average speed of this train?

As a pendulum moves closer to the equilibrium position, how do the velocity, acceleration, and force change? the velocity decreases, the acceleration decreases, and the net force decreases. the velocity increases, the acceleration decreases, and the net force decreases. the velocity increases, the acceleration increases, and the net force decreases. the velocity decreases, the acceleration increases, and the net force increases.
