Problem: For general projectile motion, which statement is true when the projectile is at the highest point of its trajectory? A) Its velocity and acceleration are both zero. B) Its velocity is perpendicular to the acceleration. C) Its acceleration is zero. D) The horizontal component of its velocity is zero. E) The horizontal and vertical components of its velocity are zero.

FREE Expert Solution

In projectile motion:

  • The acceleration is constant (9.8 m/s2) and directed downward (negative y-axis).
  • The y-component of the velocity at the top of the trajectory is zero.
