At the highest point of its trajectory, what is the velocity of the soccer ball that was launched vertically upwards?

The velocity is at its maximum value.

The velocity is zero.

The velocity is negative.

The velocity is equal to its initial value.

Why does the velocity of the soccer ball decrease as it rises after being launched vertically?

Because the ball is gaining kinetic energy.

Because gravity acts in the opposite direction to the motion.

Because the ball is being pushed by the wind.

Because the ball is losing mass.
