Question

During a Hockey game, an attacking player shoots a low hard shot into the goal. The ball leaves the Hockey stick and travels into the net very quickly. What happens if he would have hit the ball such that it flies toward the goal?

• A. The horizontal acceleration of the ball increases
• B. The vertical acceleration of the ball increases
• C. The horizontal velocity of the ball is constant
• D. The vertical velocity of the ball is constant
• E. All the listed quantities are constant

Answer 1

Answer: (C)

The horizontal velocity of the ball is constant

In both conditions , ball is hit by the same force and also in both cases ball will follow projectile path as we know that in projectile motion horizontal component of velocity remains constant because there is no horizontal acceleration therefore horizontal velocity of the ball is constant.
