A. The horizontal component of velocity remains constant.B. The vertical acceleration is constant and downward.C. The trajectory is parabolic.D. The speed remains constant throughout.
Correct Answer: A|B|C
Explanation:
Only the velocity direction and vertical component change; speed is not generally constant.
A. Acceleration is proportional to displacement and opposite in direction.B. Speed is maximum at the mean position.C. Potential energy is maximum at an extreme position.D. Acceleration is zero at every extreme position.
Correct Answer: A|B|C
Explanation:
At the extremes acceleration magnitude is maximum, not zero.
