Meixiu is at the park with her friend Joey from physics class. They want to understand projectile motion, so they are using a pitching machine to launch baseballs, and observe the baseball's trajectories for different scenarios. Later, they use this simulation to help them understand what they observed. In this simulation, the friends can observe the parabolic path of a projectile launched from the origin. The velocity vector, as well as its horizontal and vertical components, is shown at all points along the path. They can use the sliders to adjust the initial speed and launch angle of the projectile, then click "fire" to launch. They note that in this simulation, air resistance is ignored, although in reality air resistance does play a role in a projectile's motion. Initial Speed 40 m/s y (m) 50 45 40 35 30 25 20 15 V, 10 Vyi x (m) Launch Angle 50 degrees 90 75 60 Time- 0.00s fire раuse clear Click here to open the simulation in a new window. Part 1 of 11 - Horizontal and Vertical Components of the Velocity Vector Meixiu asks Joey to describe the horizontal and vertical components of the velocity vector along the baseball's path. Which of Joey's responses is correct? O The x component remains constant." O The x component equals the initial y component, and the y component equals the initial x component." O The final y component is equal to the initial y component in magnitude and direction." O Just before the baseball hits the ground, both components are equal in magnitude and opposite in direction to their initial values." Iulululmululululul
