Question

question 5 (3 points) a baseball is thrown from the outfield toward the catcher. when the ball reaches its highest point, which statement is true? its velocity and its acceleration are both zero. its velocity is not zero, but its acceleration is zero. its velocity is perpendicular to its acceleration. its acceleration depends on the angle at which the ball was thrown. none of the above statements are true. question 6 (2 points) as a projectile moves in its path, the velocity and acceleration vectors will be perpendicular to each other at the end of the motion at no point during the motion at the start of the motion at the top of the parabolic (projectile) motion

Explanation:

For Question 5, when a baseball reaches its highest - point in projectile motion, the vertical component of velocity is zero, but it still has a non - zero horizontal component of velocity. The acceleration is due to gravity and is always \(g = 9.8\ m/s^{2}\) (downward), so the velocity (horizontal) is perpendicular to the acceleration (downward).
For Question 6, in projectile motion, at the top of the parabolic path, the vertical component of velocity is zero and the velocity is entirely horizontal while the acceleration due to gravity is downward, making the velocity and acceleration vectors perpendicular.

Answer:

Question 5: Its velocity is perpendicular to its acceleration.
Question 6: At the top of the parabolic (projectile) motion
