Question

The package follows a cured path, but it is always vertically below the airplane. The package follows a straight line path that lags behind the airplane. A car travels due east at 12 m/s. It makes a turn due north and continues to travel at 16 m/s. What is the net velocity of the car? 20 m/s, 53 degree with the east 25 m/s, 37 degree with the east 28 m/s, 35 degree with the east 31 m/s, 45 degree with the east 25 m/s, 53 degree with the east A baseball is hit upward and travels along a parabolic arc before it strikes the ground. Which one of the following statements is necessarily true? The x-component of the velocity of the ball varies throughout the ball's flight The acceleration of the ball decreases as the ball moves upward The y-component of the velocity of the ball is zero when the ball is at the highest point The velocity of the ball is a maximum when the ball is at the highest point in the arc The acceleration of the ball is zero when the ball is at the highest point in the arc A spacecraft is traveling with a velocity of +4349.7 m/s.
