You toss a basketball toward the basket. at the highest point of its arc.

the vertical component of the velocity is zero.
the horizontal component of the velocity is zero.
both the horizontal and vertical components of the velocity are zero.

The vertical component of the velocity is zero.

Explanation:

The motion of the basketball is the motion of a projectile, which consists of two independent motions:

- A uniform motion along the horizontal direction, with constant horizontal velocity

- An uniformly accelerated motion along the vertical direction, with downward constant acceleration g = 9.8 m/s^2

As a result, we have:

- The horizontal component of the velocity does not change throughout the motion, so it is always the same, even at the highest point of the trajectory (therefore it is not zero)

- The vertical component of the velocity decreases at first, then at the highest point of the trajector becomes zero, then changes direction (downward) and starts increasing again in magnitude

So, the correct option is

The vertical component of the velocity is zero.
