The acceleration of a particle in projectile motion A. points along the parabolic path of the particle. B. is directed horizontally. C. vanishes at the particle's highest point. D. is vertically downward. E. is zero.
For general projectile motion, when the projectile is at the highest point of its motion: a) the horizontal component of its velocity is zero. b) its velocity is parallel to the acceleration. c) its velocity and acceleration are both zero. d) the horizontal and vertical components of its velocity are both zero. e) its velocity is perpendicular to the acceleration.
In ideal projectile motion, the velocity and acceleration of the projectile at its maximum height are, respectively, a) horizontal, vertical downward. b) horizontal, zero. c) zero, zero. d) zero, vertical downward. e) zero, horizontal.
